As mentioned earlier, for Windows users there is a fake sendmail option. A bit more detailed description how to do this is:

If you have a test server in use running Windows and some kind of WAMP combo (XXAMP, WAMP Server, etc) then you'll notice that the PHP sendmail command (mail()) does not work. Windows simply does not provide the sendmail statement ...

There is a simple trick to get this to work though;

1) Download (or use the attached file) from

2) Unzip this in a folder on your c: drive (preferably use a simple path, for example c:\wamp\sendmail -- long filenames could cause problems)

3) Edit your PHP.INI file (note: WAMP users should access their php.ini file from the WAMP menu). Go to the [mail function] section and modify it as such:

[mail function]
; For Win32 only.

; For Win32 only.
;sendmail_from =

; For Unix only. You may supply arguments as well (default: "sendmail -t -i").
sendmail_path = "C:\wamp\sendmail\sendmail.exe -t"

; Force the addition of the specified parameters to be passed as extra parameters
; to the sendmail binary. These parameters will always replace the value of
; the 5th parameter to mail(), even in safe mode.
;mail.force_extra_paramaters =

.. and save the changes.

4) Open the sendmail.ini and modify the settings to:


; you must change to your smtp server,
; or to IIS's "pickup" directory. (generally C:\Inetpub\mailroot\Pickup)
; emails delivered via IIS's pickup directory cause sendmail to
; run quicker, but you won't get error messages back to the calling
; application.

; smtp port (normally 25)


; the default domain for this server will be read from the registry
; this will be appended to email addresses when one isn't provided
; if you want to override the value in the registry, uncomment and modify

; log smtp errors to error.log (defaults to same directory as sendmail.exe)
; uncomment to enable logging
; error_logfile=sendmail_error.log

; create debug log as debug.log (defaults to same directory as sendmail.exe)
; uncomment to enable debugging
; debug_logfile=sendmail_debug.log

; if your smtp server requires authentication, modify the following two lines


; if your smtp server uses pop3 before smtp authentication, modify the
; following three lines

; to force the sender to always be the following email address, uncomment and
; populate with a valid email address. this will only affect the "MAIL FROM"
; command, it won't modify the "From: " header of the message content

; sendmail will use your hostname and your default_domain in the ehlo/helo
; smtp greeting. you can manually set the ehlo/helo name if required


The optional error and debug logging is recommended when trying this the first time, so you have a clue what goes wrong in case it doesn't work.
Force_sender is also optional, but recommended to avoid confusion on the server end.
Obviously,, and mysecretpassword should be the relevant info for your SMTP server.
Now restart the WAMP services (mainly Apache so PHP re-reads it's config).

Now you're good to go and use the PHP mail() statement as if you're a Unix user ...

Corrupted Attachments ???
I spent many hours with corrupted attachments (of all types of files) - The answer: a blank line is needed after $msg.=$file \r\n \r\n [incredible but true].
Heres some useful code for sending an attachment, and display html OR text depending on the users email-reader.

i work with many different systems, so...

<?php # Is the OS Windows or Mac or Linux
if (strtoupper(substr(PHP_OS,0,3)=='WIN')) {
} elseif (
strtoupper(substr(PHP_OS,0,3)=='MAC')) {
} else {

# File for Attachment
$f_name="../../letters/".$letter; // use relative path OR ELSE big headaches. $letter is my file for attaching.
$handle=fopen($f_name, 'rb');
$f_contents=fread($handle, filesize($f_name));
$f_contents=chunk_split(base64_encode($f_contents)); //Encode The Data For Transition using base64_encode();
# To Email Address
# Message Subject
$emailsubject="Heres An Email with a PDF".date("Y/m/d H:i:s");
# Message Body
"emailbody.php"); // i made a simple & pretty page for showing in the email
$body=ob_get_contents(); ob_end_clean();

# Common Headers
$headers .= 'From: Jonny <>'.$eol;
$headers .= 'Reply-To: Jonny <>'.$eol;
$headers .= 'Return-Path: Jonny <>'.$eol; // these two to set reply address
$headers .= "Message-ID:<".$now." TheSystem@".$_SERVER['SERVER_NAME'].">".$eol;
$headers .= "X-Mailer: PHP v".phpversion().$eol; // These two to help avoid spam-filters
# Boundry for marking the split & Multitype Headers
$headers .= 'MIME-Version: 1.0'.$eol;
$headers .= "Content-Type: multipart/related; boundary=\"".$mime_boundary."\"".$eol;
$msg = "";

# Attachment
$msg .= "--".$mime_boundary.$eol;
$msg .= "Content-Type: application/pdf; name=\"".$letter."\"".$eol; // sometimes i have to send MS Word, use 'msword' instead of 'pdf'
$msg .= "Content-Transfer-Encoding: base64".$eol;
$msg .= "Content-Disposition: attachment; filename=\"".$letter."\"".$eol.$eol; // !! This line needs TWO end of lines !! IMPORTANT !!
$msg .= $f_contents.$eol.$eol;
# Setup for text OR html
$msg .= "Content-Type: multipart/alternative".$eol;

# Text Version
$msg .= "--".$mime_boundary.$eol;
$msg .= "Content-Type: text/plain; charset=iso-8859-1".$eol;
$msg .= "Content-Transfer-Encoding: 8bit".$eol;
$msg .= "This is a multi-part message in MIME format.".$eol;
$msg .= "If you are reading this, please update your email-reading-software.".$eol;
$msg .= "+ + Text Only Email from Genius Jon + +".$eol.$eol;

# HTML Version
$msg .= "--".$mime_boundary.$eol;
$msg .= "Content-Type: text/html; charset=iso-8859-1".$eol;
$msg .= "Content-Transfer-Encoding: 8bit".$eol;
$msg .= $body.$eol.$eol;

# Finished
$msg .= "--".$mime_boundary."--".$eol.$eol; // finish with two eol's for better security. see Injection.

ini_set(sendmail_from,''); // the INI lines are to force the From Address to be used !
mail($emailaddress, $emailsubject, $msg, $headers);

I hope this helps.

In case you don't want to, or can't, configure sendmail for your server, a good alternative is esmtp - it's an smtp mailer with minimum configuration that can be used as a sendmail drop-in :

I spent hours searching the web trying to figure out why I was getting a "WARNING: mail(): SMTP server response: 501 5.5.4 Invalid Address " every time I was using the mail() function on my server (Win2K3,IIS 6.0,PHP4.4.1). I knew everything was setup properly for SMTP based on other non IIS 6.0 configurations.

Turns out that the IIS 6.0 SMTP service does not like formatting of the "From" field in mail headers. For instance:
//This line DOES NOT send mail message correctly
$headers .= "From: \"".$fromname."\" <".$fromaddress.">\n";
However this works:
//This line sends mail message correctly
$headers .= "From: \"".$fromaddress."\"\n";

The fix is in Microsoft Article ID 291828 ( ). Even though the "bug" workaround is for IIS 6.0 on Exchange 2003 communicating with a UNIX server, THIS SOLVES THE PROBLEM. Just skip down to the last section for Exchange 2003 and follow the instructions to modify the IIS 6 MetaBase with the MetaBase Explorer found in the IIS 6 Resource Kit.

For those of you with the exim, if its not sending mail with the -i option and you cant easily change this, you might want to check out the imap_mail() function which works almost exactly the same and doesnt use exim, most web hosts provide this. If you using your own server then php needs to be compiled with imap libraries etc.

For anyone having problems with attached files coming through garbled, make sure you have magic_quotes_runtime set to Off in your php.ini - it adds funky escape chars to your attached data and garbles the attachment.

This was giving me all kinds of grief.

If using a chroot environment and you don't want to have a full mailer in it, mini-sendmail (can be found at is very useful. It is just a small binary that sends mails over your local mta over port 25.

Suggestion for methods checking form inputs for e-mail injection attempts.

Any inputs expected from single-line text fields can just be refused if they contain a newline character. The second function tries to minimize matches on non-evil inputs by matching suspect strings only if preceded by a newline character. (Anyway, if this is considered to be safe, it will of course do it for single-line inputs, too.)


* Check single-line inputs:
* Returns false if text contains newline character
function has_no_newlines($text)
preg_match("/(%0A|%0D|\\n+|\\r+)/i", $text) == 0;

* Check multi-line inputs:
* Returns false if text contains newline followed by
* email-header specific string
function has_no_emailheaders($text)
preg_match("/(%0A|%0D|\\n+|\\r+)(content-type:|to:|cc:|bcc:)/i", $text) == 0;
