(PHP 4, PHP 5, PHP 7)

mailTrimite mesaje e-mail

Descrierea

mail ( string $to , string $subject , string $message [, mixed $additional_headers [, string $additional_parameters ]] ) : bool

Trimite un mesaj e-mail.

Parametri

to

Destinatarul sau destinatarii mesajului.

Formatul acestui string trebuie să respecte » RFC 2822. Unele exemple:

  • user@example.com
  • user@example.com, anotheruser@example.com
  • User <user@example.com>
  • User <user@example.com>, Another User <anotheruser@example.com>

subject

Subiectul mesajului spre a fi trimis.

Precauţie

Subiectul trebuie să satisfacă cerințelor » RFC 2047.

message

Mesajul spre a fi trimis.

Fiecare rând trebuie să fie încheiat cu CRLF (\r\n). Lungimea rândurilor nu trebuie să depășească 70 de caractere.

Precauţie

(Numai pentru Windows) Când PHP conlucrează direct cu un server SMTP, dacă este întâlnit un punct la începutul unui rând, el este eliminat. Pentru a depăși aceste situații, dublați punctul de la începutul rândului.

<?php
$text 
str_replace("\n.""\n.."$text);
?>

additional_headers (opțional)

Un string sau array spre a fi inserat la sfârșitul antetelor mesajului.

Acesta este utilizat de obicei pentru a adăuga antete suplimentare (From, Cc, și Bcc). Antetele suplimentare multiple trebuie separate cu CRLF (\r\n). Dacă pentru a stabili acest antet se folosesc date externe, ele trebuie filtrate, astfel încât să nu fie posibilă inserarea antetelor nedorite.

Dacă este transmis un array, atunci cheile sale sunt denumirile antetelor, iar valorile sale sunt valorile antetelor respective.

Notă:

Înainte de PHP 5.4.42 și 5.5.27, respectiv, additional_headers nu avea o protecție împotriva injectării antetelor de email. De aceea utilizatorii trebuie să se asigure că antetele specificate sunt în siguranță și că conțin doar antete. De ex. niciodată nu începeți corpul mesajului inserând mai multe linii noi.

Notă:

La trimiterea mesajului, acesta trebuie să conțină antetul From. Acesta poate fi stabilit cu ajutorul parametrului additional_headers, sau poate fi stabilită o valoare implicită în php.ini.

În caz că nu se respectă această condiție, se va produce un mesaj de eroare similar cu acesta: Warning: mail(): "sendmail_from" not set in php.ini or custom "From:" header missing Antetul From stabilește de asemenea Return-Path când mesajul este transmis direct prin SMTP (doar în Windows).

Notă:

Dacă mesajele nu sunt primite, încercați să utilizați numai LF (\n). Unii agenți de transfer a mesajelor în Unix (în special » qmail) înlocuiesc LF cu CRLF în mod automat (ceea ce duce la dublarea CR dacă este utilizat CRLF). Utilizați acest procedeu numai în caz excepțional, deoarece acesta nu se conformaeză cu » RFC 2822.

additional_parameters (opțional)

Parametrul additional_parameters poate fi utilizat pentru a transmite fanioane suplimentare programului configurat pentru a transmite poșta, definit de opțiunea de configurare sendmail_path. Spre exemplu, acesta poate fi utilizat pentru a stabili adresa expeditorului de pe plic când se utilizează sendmail cu opțiunea -f.

Acest parametru este filtrat cu escapeshellcmd() în mod automat pentru a preveni execuția comenzilor. escapeshellcmd() previne execuția comenzilor, dar permite adăugarea parametrilor suplimentari. Din punct de vedere al securității este recomandabil ca utilizatorul să filtreze și să verifice acest parametru pentru a evita adăugarea parametrilor nedoriți la comanda pentru înveliș.

Deoarece escapeshellcmd() este aaplicată în mod automat, unele caractere care sunt permise în adrese email de standardele RFC, nu pot fi utilizate. Funcția mail() nu poate permite asemenea caractere, de aceea în programele în care este necesară utilizarea acestor caractere, se recomandă utilizarea metodelor alternative de transmitere a email-urilor (de ex. utilizarea unui framework sau a unei biblioteci).

Utilizatorul cu care rulează serveul web trebuie adăugat în calitate de utilizator de încredere în configurația sendmail pentru a preveni adăugarea unui antet 'X-Warning' la mesaj atunci când expeditorul de pe plic (-f) este stabilit prin această metodă. Pentru utilizatorii sendmail acest fișier este /etc/mail/trusted-users.

Valorile întoarse

Întoarce TRUE dacă mesajul a fost acceptat cu succes pentru trimitere, FALSE în caz contrar.

Este important să știți că cu toate că mesajul a fost acceptat spre trimitere, aceasta NU înseamnă că mesajul într-adevăr va ajunge la destinație.

Istoricul schimbărilor

Versiune Descriere
7.2.0 Parametrul additional_headers acum acceptă și un array.

Exemple

Example #1 Trimiterea mesajelor.

Utilizarea mail() pentru a transmite un mesaj simplu:

<?php
// Mesajul
$message "Line 1\r\nLine 2\r\nLine 3";

// În caz că vre-un rând depășește 70 de caractere, trebuie să utilizăm
// wordwrap()
$message wordwrap($message70"\r\n");

// Trimiterea
mail('caffeinated@example.com''My Subject'$message);
?>

Example #2 Trimiterea unui mesaj cu antete suplimentare.

Adăugarea antetelor de bază, transmițându-i MUA adresele From și Reply-To:

<?php
$to      
'nobody@example.com';
$subject 'the subject';
$message 'hello';
$headers 'From: webmaster@example.com' "\r\n" .
    
'Reply-To: webmaster@example.com' "\r\n" .
    
'X-Mailer: PHP/' phpversion();

mail($to$subject$message$headers);
?>

Example #3 Transmiterea unui mesaj cu antete suplimentare în array

Acest exemplu transmite același mesaj ca și exemplul anterior, dar transmite antetele adiționale într-un tablou (disponibil începând cu PHP 7.2.0).

<?php
$to      
'nobody@example.com';
$subject 'the subject';
$message 'hello';
$headers = array(
    
'From' => 'webmaster@example.com',
    
'Reply-To' => 'webmaster@example.com',
    
'X-Mailer' => 'PHP/' phpversion()
);

mail($to$subject$message$headers);
?>

Example #4 Trimiterea unui mesaj cu un parametru suplimentar în linia de comandă.

Parametrul additional_parameters poate fi utilizat pentru a transmite un parametru suplimentar programului configurat pentru a fi utilizat la trimiterea poștei cu ajutorul sendmail_path.

<?php
mail
('nobody@example.com''the subject''the message'null,
   
'-fwebmaster@example.com');
?>

Example #5 Transmiterea unui mesaj HTML

Este posibil de a trimite mesaje HTML cu mail().

<?php
// Destinatari multipli
$to 'johny@example.com, sally@example.com'// observați virgula

// Subiectul
$subject 'Birthday Reminders for August';

// Mesajul
$message '
<html>
<head>
  <title>Birthday Reminders for August</title>
</head>
<body>
  <p>Here are the birthdays upcoming in August!</p>
  <table>
    <tr>
      <th>Person</th><th>Day</th><th>Month</th><th>Year</th>
    </tr>
    <tr>
      <td>Johny</td><td>10th</td><td>August</td><td>1970</td>
    </tr>
    <tr>
      <td>Sally</td><td>17th</td><td>August</td><td>1973</td>
    </tr>
  </table>
</body>
</html>
'
;

// Pentru a trimite mesaje HTML, trebuie stabilit antetul Content-type
$headers[] = 'MIME-Version: 1.0';
$headers[] = 'Content-type: text/html; charset=iso-8859-1';

// Antete suplimentare
$headers[] = 'To: Mary <mary@example.com>, Kelly <kelly@example.com>';
$headers[] = 'From: Birthday Reminder <birthday@example.com>';
$headers[] = 'Cc: birthdayarchive@example.com';
$headers[] = 'Bcc: birthdaycheck@example.com';

// Trimiterea mesajului
mail($to$subject$messageimplode("\r\n"$headers));
?>

Notă:

Dacă se intenționează trimiterea mesajelor HTML, sau a altor mesaje complexe, este recomandată utilizarea pachetului PEAR » PEAR::Mail_Mime.

Note

Notă:

Implementarea SMTP (doar în Windows) a funcției mail() diferă în multe aspecte de implementarea sendmail. În primul rând ea nu utilizează un binar local pentru a compune mesajele, dar operează direct asupra socket-urilor, ceea ce înseamnă că este necesar ca un MTA să asculte pe un socket de rețea (care poate fi pe serverul local sau pe unul îndepărtat).

În al doilea rând, antetele personalizate, cum ar fi From:, Cc:, Bcc: și Date: nu sunt interpretate de către MTA în primul rând, dar sunt procesate de PHP.

Prin urmare, parametrul to nu trebuie să fie o adresă de forma "Ceva <cineva@exemplu.com>". Comanda mail poate să nu prelucreze aceasta în mod corect în timp ce conlucrează cu MTA.

Notă:

Face de menționat că funcția mail() nu este potrivită pentru volume mari de masaje trimise consecutiv. Această funcție deschide și închide socket-ul SMTP pentru fiecare mesaj, ceea ce nu este foarte eficient.

Pentru transmiterea volumelor mari de mesaje considerați pachetele » PEAR::Mail și » PEAR::Mail_Queue.

Notă:

Următoarele RFC-uri pot fi de folos: » RFC 1896, » RFC 2045, » RFC 2046, » RFC 2047, » RFC 2048, » RFC 2049 și » RFC 2822.

Often it's helpful to find the exact error message that is triggered by the mail() function. While the function doesn't provide an error directly, you can use error_get_last() when mail() returns false.

<?php
$success
= mail('example@example.com', 'My Subject', $message);
if (!
$success) {
   
$errorMessage = error_get_last()['message'];
}
?>

(Tested successfully on Windows which uses SMTP by default, but sendmail on Linux/OSX may not provide the same level of detail.)

If you notice wrong displayed characters in the email it's because you need to properly set the Content-Type and the Charset in the headers of the email:

<?php
$headers
= 'Content-Type: text/plain; charset=utf-8' . "\r\n";
?>

Mostly, UTF-8 is your best choice.

You can set custom headers with the fourth parameter of the mail() function.

To make the whole thing waterproof, add the following header too:

<?php
$headers
.= 'Content-Transfer-Encoding: base64' . "\r\n";
?>

Now you can use the combination of UTF-8 and Base64 to properly encode the subject line and the recipient name like this:

<?php
$subject
= '=?UTF-8?B?' . base64_encode('Test email with German Umlauts öäüß') . '?=';
$recipient = '=?UTF-8?B?' . base64_encode('Margret Müller') . '?= <recipient@domain.com>';
?>

And don't forget to Base64 encode the email message too:

<?php
$message
= base64_encode('This email contains German Umlauts öäüß.');
?>

Security advice: Although it is not documented, for the parameters $to and $subject the mail() function changes at least \r and \n to space. So these parameters are safe against injection of additional headers. But you might want to check $to for commas as these separate multiple addresses and you might not want to send to more than one recipient.

The crucial part is the $additional_headers parameter. This parameter can't be cleaned by the mail() function. So it is up to you to prevent unwanted \r or \n to be inserted into the values you put in there. Otherwise you just created a potential spam distributor.

The 'sendmail' executable which PHP uses on Linux/Mac (not Windows) expects "\n" as a line separator.

This executable is a standard, and emulated by other MTAs.

"\n" is confirmed required for qmail and postfix, probably also for sendmail and exim but I have not tested.

If you pass through using "\r\n" as a separator it may appear to work, but your email will be subtly corrupted and some middleware may break. It only works because some systems will clean up your mistake.

If you are implementing DKIM be very careful, as DKIM checks will fail (at least on popular validation tools) if you screw this up. DKIM must be calculated using "\r\n" but then you must switch it all to "\n" when using the PHP mail function.

On Windows, however, you should use "\r\n" because PHP is using SMTP in this situation, and hence the normal rules of the SMTP protocol (not the normal rules of Unix piping) apply.

It is worth noting that you can set up a fake sendmail program using the sendmail_path directive in php.ini.

Despite the comment in that file, sendmail_path also works for Window. From https://www.php.net/manual/en/mail.configuration.php#ini.sendmail-path:

This directive works also under Windows. If set, smtp, smtp_port and sendmail_from are ignored and the specified command is executed.

I migrated an application to a platform without a local transport agent (MTA). I did not want to configure an MTA, so I wrote this xxmail function to replace mail() with calls to a remote SMTP server. Hopefully it is of some use.

function xxmail($to, $subject, $body, $headers)
{
$smtp = stream_socket_client('tcp://smtp.yourmail.com:25', $eno, $estr, 30);

$B = 8192;
$c = "\r\n";
$s = 'myapp@someserver.com';

fwrite($smtp, 'helo ' . $_ENV['HOSTNAME'] . $c);
  $junk = fgets($smtp, $B);

// Envelope
fwrite($smtp, 'mail from: ' . $s . $c);
  $junk = fgets($smtp, $B);
fwrite($smtp, 'rcpt to: ' . $to . $c);
  $junk = fgets($smtp, $B);
fwrite($smtp, 'data' . $c);
  $junk = fgets($smtp, $B);

// Header
fwrite($smtp, 'To: ' . $to . $c);
if(strlen($subject)) fwrite($smtp, 'Subject: ' . $subject . $c);
if(strlen($headers)) fwrite($smtp, $headers); // Must be \r\n (delimited)
fwrite($smtp, $headers . $c);

// Body
if(strlen($body)) fwrite($smtp, $body . $c);
fwrite($smtp, $c . '.' . $c);
  $junk = fgets($smtp, $B);

// Close
fwrite($smtp, 'quit' . $c);
  $junk = fgets($smtp, $B);
fclose($smtp);
}

Note that there is a big difference between the behavior of this function on Windows systems vs. UNIX systems. On Windows it delivers directly to an SMTP server, while on a UNIX system it uses a local command to hand off to the system's own MTA.

The upshot of all this is that on a Windows system your  message and headers must use the standard line endings \r\n as prescribed by the email specs. On a UNIX system the MTA's "sendmail" interface assumes that recieved data will use UNIX line endings and will turn any \n to \r\n, so you must supply only \n to mail() on a UNIX system to avoid the MTA hypercorrecting to \r\r\n.

If you use plain old \n on a Windows system, some MTAs will get a little upset. qmail in particular will refuse outright to accept any message that has a lonely \n without an accompanying \r.

Make sure you enclose \r\n in double quotes (not single quotes!) so that PHP can translate that into the correct linefeed code

Here's a small handy function I use to send email in UTF-8.

<?php
function mail_utf8($to, $from_user, $from_email,
                                            
$subject = '(No subject)', $message = '')
   {
     
$from_user = "=?UTF-8?B?".base64_encode($from_user)."?=";
     
$subject = "=?UTF-8?B?".base64_encode($subject)."?=";

     
$headers = "From: $from_user <$from_email>\r\n".
              
"MIME-Version: 1.0" . "\r\n" .
              
"Content-type: text/html; charset=UTF-8" . "\r\n";

     return
mail($to, $subject, $message, $headers);
   }
?>

I was having delivery issues from this function to Gmail, Yahoo, AOL, etc.  I used the notes here to figure that you need to be setting your Return-Path to a valid email to catch bounces.  There are two extra delivery gotchas on top of that:

1) The domain in the email used in the -f option in the php.ini sendmail parameter or in the mail() extra parameters field, needs to have a valid SPF record for the domain (in DNS as a "TXT" record type for sure and add an additional  "SPF" type record if possible).  Why? That's header field being used for spam checks.

2) You should also use a domain key or DKIM.  The trick here is that the domain key/DKIM is case sensitive!  I used Cpanel to create my domain key which automatically used all lowercase domain names in the key creation.  I found when  sending email and using a camel case "-f account@MyDomainHere.Com" option, my key was not accepted.  However it was accepted when I used "-f account@mydomainhere.com".

There are many other factors that can contribute to mail not getting to inboxes, including your own multiple failed testing attempts, so I suggest you consult each site's guidelines and don't ask me for help.  These are just the couple technical issues that helped my case.

I hope this saves someone some time and headaches...

I recently changed hosting companies and spent a day trying to see why an email script that had been working for years failed on the new server.

The answer was that the old hosting company's email server accepted multiple "CC:" lines in the additional headers string, and the new did not. Thus on the new server

...
$add_hdr .= "CC: " . $email1 . PHP_EOL;
$add_hdr .= "CC: " . $email2 . PHP_EOL;
...

did not work, but

...
$add_hdr .= "CC: " . $email1 . ", " . $email2 . PHP_EOL;
...

did work.

In both cases, PHP's mail() function returned no error, but until I placed both emails, comma-separated, in the same line I was getting the following error:

550 Messages should have one or no Cc headers, not 2.

Hope this helps someone.

I found I needed to use the additional parameter -f$envelope_sender to send subscribe messages to my email list manager (Enemies of Carlotta, YMMV). Simply setting From: email@address.tld in additional headers wasn't sufficient.

So to subscribe to mylist@example.com via a PHP script I call
mail("mylist-subscribe@example.com", $emailSubject, $body, '', "-f$email_to_subscribe");

Be careful to not put extra spaces for the $headers variable.

For example, this didn't work on our servers:

$headers = "From: $from \r\n Bcc: $bcc \r\n";

But this did:

$headers = "From: $from\r\nBcc: $bcc\r\n";

Notice the removal of the spaces around the first \r\n.

To define a mail sensitivity you have to put this line in the headers:

<?php
        $headers
= "MIME-Version: 1.0\n" ;
       
$headers .= "Content-Type: text/html; charset=\"iso-8859-1\"\n";

       
$headers .= "Sensitivity: Personal\n";

$status   = mail($to, $subject, $message,$headers);
?>

Possible Options:
Sensitivity: Normal, Personal, Private and Company-Confidential

These will be recognised and handled in Outlook, Thunderbird and others.

Currently my hosting service is on Godaddy. When attempting to use the mail function without the fifth parameter containing "-f", my message headers would not work.

Whenever your message headers do not work, simply try using the fifth parameter:

<?php
mail
($to, $subject, $message, $headers, "-femail.address@example.com");
?>

I have tried many online tutorials to get mail() function working in windows, until i stumbled upon this website
http://php.codeindepth.com/php-sending-mail/

It really boils down to changing few directives in php.ini and sendmail.ini

Changes required in sendmail.ini

smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
auth_username=your-gmail-id@gmail.com
auth_password=your-gmail-password
force_sender=your-gmail-id@gmail.com

Changes required in php.ini

SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = your-gmail-id@gmail.com
sendmail_path = "\"C:\xampp\sendmail\sendmail.exe\" -t"
;sendmail_path = "C:\xampp\mailtodisk\mailtodisk.exe"

Just a comment on some of the examples, and as a note for those who may be unaware. The SMTP RFC 822 is VERY explicit in stating that \r\n is the ONLY acceptable line break format in the headers, though is a little vague about the message body. While many MTAs will deal with just \n, I've run accross plenty of them that will exhibit "interesting" behaviours when this happens. Those MTAs that are strict in compliance will definitely break when header lines are terminated with only \n. They will also most likely break if the body of the message contains more than 1000 consecutive characters without a \r\n.*

Note that RFC 821 is a little more clear in defining:
"line
      A a sequence of ASCII characters ending with a <CRLF>."

RFC 821 makes no distinction between header lines and message body lines, since both are actually transmitted during the DATA phase.

Bottom line, best practice is to be sure to convert any bare \n characters in the message to \r\n.

* "The maximum total length of a text line including the <CRLF> is 1000 characters" (RFC 821)

If you are using the sendmail app from an exim package or something you don't really need to change the normal parameters PHP gives it (-t -i) as other posts described.

I just added "-f myemail@example.com" and it worked.

One thing that got me stuck for a few hours was trying to figure out why the return-path was set as the user (user running php) and not what I was setting it with the -f option then I later found at that in order to forcefully set the return-path the user account running the command must be in exim's trusted users configuration! It helps to add trusted_groups as well then everything works fine :)

Note, that single line should not contain more than 78 character, but is not allowed to contain more than 998 characters.

The possible consequences are:
Over 78 - clients are allowed to display the message in a "harder to read" way.
Over 998 - clients and servers are allowed to drop the message or cause any buffer-limit error.

When dealing with mail headers "\n" and "\r\n" *sometimes* makes a big difference.

Once our CentOs servers got re-installed, all headers like:

  $headers = "MIME-Version: 1.0\r\n";
  $headers.= "Content-type: text/html; charset=iso-8859-1\r\n";
...

became part of message body instead of headers

I was able to fixed this by replacing "\r\n" with just "\n"

***Encoding plain text as quoted-printable in MIME email***

If you don't want to install IMAP and use imap_8bit() to encode plain text or html message as quoted-printable
(friendly french special characters encoding :-) in MIME email, try this function.
I haven't fully tested it ( like with microtime with long mails). I send html message as 7-bit, so I didn't try yet with html.
If you have good html practise, you don't really need to encode html as quote-printable as it only uses 7-bit chars.

Bare LFs in SMTP

Use This

<?php
// Fix any bare linefeeds in the message to make it RFC821 Compliant.
$message = preg_replace("#(?<!\r)\n#si", "\r\n", $message);
   
// Make sure there are no bare linefeeds in the headers
$headers = preg_replace('#(?<!\r)\n#si', "\r\n", $headers);
?>

When using the PHP mail() function with IIS 6 on Windows Server 2003, check your "Relay" settings on the SMTP Virtual Server in IIS.  If you grant access to 127.0.0.1 and set then set your php.ini SMTP to the same IP address (along with setting the same port 25), you should have success in sending mail. 

I'm using PHP 5.3 and have had success with this configuration and did not have to define the "sendmail_from" setting in our php.ini file.

This is for Windows Server 2003, IIS 6.0 with SMTP virtual server.

The problem I had was not including init_set for the SMTP server, I thought the SMTP definition in the IIS SMTP virtual server configuration would work.  When I sent mail manually this was not an issue. 

Also, $mail_sent = @mail( $to, $subject, $message, $headers ); wouldn't work but $mail_sent = mail($to, $subject, $message, $headers); did.
Lack of date_default_timezone_set() only caused a warning because php guessed what it should be.

This worked:
<?php
$to     
= 'nobody@example.com';
$subject = 'the subject';
$message = 'hello';
$headers = 'From: webmaster@example.com' . "\r\n" .
   
'Reply-To: webmaster@example.com' . "\r\n" .
   
'X-Mailer: PHP/' . phpversion();
ini_set ( "SMTP", "smtp-server.example.com" );
date_default_timezone_set('America/New_York');

mail($to, $subject, $message, $headers);
?>

And just so you can troubleshoot, this worked when sending mail from the command line/manually. CLI worked even though the php code without the init_set function wouldn't work.

You will notice that the "rcpt to" and "to" fields appear redundant, but if both are not used, the delivered mail's "to" field will be blank/empty.

-------------------------------
telnet www.example.com 25
helo
mail from: webmaster@example.com
rcpt to: someone@example.com
data
to: someone@example.com
subject: test again to make sure

this is my message
.
quit

I've noticed that on some versions of PHP occasionally mail() returns the empty string for success, rather than true or false. The empty string evaluates to false.

if you use constructs like

if ( mail( ... ) ){
  # do something here on success
}

this wont work consistently.

so you need code like

$ret=mail(....)

if ( $ret == '' || $ret ){
  # do something here
}

to get consistent results.

For qmail users, I have written a function that talks directly to qmail-queue, rather than going through the sendmail wrapper used by mail(). Thus it allows more direct control over the message (for example, you can adapt the function to display "undisclosed recipients" in to the To: header). It also performs careful validation of the e-mail addresses passed to it, making it more difficult for spammers to exploit your scripts.

Please note that this function differs from the mail() function in that the from address must be passed as a _separate_ argument. It is automatically put into the message headers and _does not_ need to be included in $additional_headers.

$to can either be an array or a single address contained in a string.
$message should not contain any carriage return characters - only linefeeds.

No validation is performed on $additional_headers. This is mostly unnecessary because qmail will ignore any additional To: headers injected by a malicious user. However if you have some strange mail setup it might be a problem.

The function returns false if the message fails validation or is rejected by qmail-queue, and returns true on success.

<?php
function qmail_queue($to, $from, $subject, $message, $additional_headers = "")
{
   
// qmail-queue location and hostname used for Message-Id
   
$cmd = "/var/qmail/bin/qmail-queue";
   
$hostname = trim(file_get_contents("/var/qmail/control/me"));
   
   
// convert $to into an array
   
if(is_scalar($to))
       
$to = array($to);
   
   
// BEGIN VALIDATION
    // e-mail address validation
   
$e = "/^[-+\\.0-9=a-z_]+@([-0-9a-z]+\\.)+([0-9a-z]){2,4}$/i";
   
// from address
   
if(!preg_match($e, $from)) return false;
   
// to address(es)
   
foreach($to as $rcpt)
    {
        if(!
preg_match($e, $rcpt)) return false;
    }
   
   
// subject validation (only printable 7-bit ascii characters allowed)
    // needs to be adapted to allow for foreign languages with 8-bit characters
   
if(!preg_match("/^[\\040-\\176]+$/", $subject)) return false;
   
   
// END VALIDATION
   
    // open qmail-queue process
   
$dspec = array
    (
        array(
"pipe", "r"), // message descriptor
       
array("pipe", "r") // envelope descriptor
   
);
   
$pipes = array();
   
$proc = proc_open($cmd, $dspec, $pipes);
    if(!
is_resource($proc)) return false;
   
   
// write additional headers
   
if(!empty($additional_headers))
    {
       
fwrite($pipes[0], $additional_headers . "\n");
    }
   
   
// write to/from/subject/date/message-ID headers
   
fwrite($pipes[0], "To: " . $to[0]); // first recipient
   
for($i = 1; $i < sizeof($to); $i++) // additional recipients
   
{
       
fwrite($pipes[0], ", " . $to[$i]);
    }
   
fwrite($pipes[0], "\nSubject: " . $subject . "\n");
   
fwrite($pipes[0], "From: " . $from . "\n");
   
fwrite($pipes[0], "Message-Id: <" . md5(uniqid(microtime())) . "@" . $hostname . ">\n");
   
fwrite($pipes[0], "Date: " . date("r") . "\n\n");
   
fwrite($pipes[0], $message);
   
fwrite($pipes[0], "\n");
   
fclose($pipes[0]);
   
   
// write from address and recipients
   
fwrite($pipes[1], "F" . $from . "\0");
    foreach(
$to as $rcpt)
    {
       
fwrite($pipes[1], "T" . $rcpt . "\0");
    }
   
fwrite($pipes[1], "\0");
   
fclose($pipes[1]);
   
   
// return true on success.
   
return proc_close($proc) == 0;
}
?>

if your mail is failing (returns false) be aware that many servers are configured to kill mail going out with a bcc or cc header.

The ideal workaround is to use the smtp functions which servers allow because of its better audit trail. Alternatively call the mail function several times.

I've just spent about four hours trying to work out what I was doing wrong!!

My mime multipart/alternative messages were going ok, until I switched to qmail with php .. after years of painfull searching, I came across this on the Life With Qmail 'Gotchas' section:

G.11. Carriage Return/Linefeed (CRLF) line breaks don't work

qmail-inject and other local injection mechanisms like sendmail don't work right when messages are injected with DOS-style carriage return/linefeed (CRLF) line breaks. Unlike Sendmail, qmail requires locally-injected messages to use Unix newlines (LF only). This is a common problem with PHP scripts.

So now, I can go back to sending emails with text AND html components :)

If you want to send UTF-8 HTML letter you need to mention charset twice:

1) In message header:
<?php
$headers
.= 'Content-type: text/html; charset=utf-8' . "\r\n";
?>

2) In HTML header:
<?php
$message
= '
<html>
<head>
   <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
   <title>Fillon soutient à fond le retour d\'un Grand Prix de France</title>
</head>
<body>
   <p>Le Premier ministre François Fillon, passionné d\'automobile et pilote à ses heures, a apporté un soutien appuyé au retour d\'un Grand Prix de France au calendrier 2013 de la Formule 1, en faisant un passage-éclair vendredi sur le circuit Paul Ricard dans le Var.</p>
</body>
</html>
'
;

In this case Outlook will also "understand" that message is encoded using UTF-8.

When sending MIME email make sure you follow the documentation with the "70" characters per line...you may end up with missing characters...and that is really hard to track down...

If you use mutt, do as below,

/usr/bin/mutt -s '$subject' -f /dev/null -e 'set copy=no' -e 'set from = "{$GLOBALS[cfg][email_from]}"' -a '$attach_file_full_path' '{$GLOBALS[cfg][email_to]}' </dev/null 2>&1;

Outlook 2007 seemed to be a little finicky with me to have carriage returns in the headers. So any \r\n resulted in messages that had default apache messages sent over to me.

As soon as I removed \r from all of the headers, the script started working fine. Hope that helped.

If you're sending a large attachment, you may encounter overflow problem.
AFAIK, two common limits could be responsible.

1. Postfix message size limit.
Edit /etc/postfix/main.cf . Change the value of "message_size_limit".

2. Apache memory size limit for scripts.
Edit /etc/php.ini . Change the value of "memory_limit".

//Then reload (or restart) Postfix and Apache.
//Empirically, sending 200MB attachment requires 500MB memory.

Be careful! Raising memory limits may cause unexpected consequences, and is hence deprecated.
Recommended alternatives include:
* Pack and split attachment into several emails.
* Only include a link to the file. The receiver can download it later.
* Use IMAP/POP3 server (e.g. Dovecot).
