php.ini の設定により動作が変化します。

Mail 設定オプション
名前 デフォルト 変更可能 変更履歴
mail.add_x_header "0" PHP_INI_PERDIR PHP 5.3.0 以降で使用可能
mail.force_extra_parameters NULL PHP_INI_PERDIR PHP 5.0.0 以降で使用可能 (PHP_INI_SYSTEM|PHP_INI_PERDIR)
SMTP "localhost" PHP_INI_ALL  
smtp_port "25" PHP_INI_ALL  
sendmail_from NULL PHP_INI_ALL  
sendmail_path "/usr/sbin/sendmail -t -i" PHP_INI_SYSTEM  
PHP_INI_* モードの詳細および定義については どこで設定を行うのか を参照してください。

以下に設定ディレクティブに関する 簡単な説明を示します。

mail.add_x_header bool

X-PHP-Originating-Script を追加します。 それはスクリプトの UID を含み、その後にファイル名が続きます。

mail.log string

ログファイルへのパス。mail() がコールされるたびにこのファイルに記録します。 ログに含まれる内容は、スクリプトのフルパスと行番号、そして To アドレスとヘッダです。

mail.force_extra_parameters string

指定したパラメータを、sendmail バイナリへの追加パラメータとして強制的に渡します。 これらのパラメータは、たとえセーフモードであっても、常に mail() の第 5 パラメータの値を上書きします。

SMTP string

Windows 環境のみで使用されます: mail() 関数でメールを送信する際に使用する SMTP サーバーのホスト名または IP アドレス。

smtp_port int

Windows 環境のみで使用されます: SMTP 設定で指定したサーバーに接続するポート番号で、 デフォルトは 25 です。

sendmail_from string

SMTP 経由で直接送信されるメールにおいて "From:" に使用するメールアドレスを指定します(Windows環境のみ)。 このディレクティブは、"Return-Path:" ヘッダも設定します。

sendmail_path string

sendmail プログラムを探すパスを指定します。 通常、/usr/sbin/sendmail または /usr/lib/sendmail です。 configure は、このパスを探し、 デフォルト値として設定しますが、 これで上手くいかない場合にはこのオプションで設定する必要があります。

sendmail を使用していないシステムは、 使用するメールシステムが提供する sendmail のラッパー/代替品を、 必要に応じてこのディレクティブに設定する必要があります。例えば、» Qmail ユーザーは、通常 /var/qmail/bin/sendmail または /var/qmail/bin/qmail-inject に設定します。

qmail-inject では、 メールを正しく処理するためのオプション設定は不要です。

このディレクティブは Windows 環境でも動作します。指定された場合は smtp および smtp_portsendmail_from の値は無視され、 ここで指定したコマンドが実行されます。

On Ubuntu 13.04, not sure of the other Distros.

If you simply uncomment the default:

sendmail_path = "sendmail -t -i"

Your mail() functions will all fail.  This is because, you should place the FULL PATH (i.e.  /usr/sbin/sendmail -t -i )

The documentation states PHP tries it's best to find the correct sendmail path, but it clearly failed for me.

So, always enter in the FULLPATH to sendmail or you may get unexpected failing results.

As a secondary note:  Those that just want to ENFORCE the -f parameter, you can do so in php.ini using:

mail.force_extra_parameters = -fdo_not_reply@domain.tld

You can leave the sendmail path commented out, it will still use the defaults  (under UNIX  -t -i options which if you look them up are very important to have set)....

But, now there is no way to change this, even with the 5th argument of the mail() function.  -f is important, because if NOT set, will be set to which ever user the PHP script is running under, and you may not want that.

Also, -f  sets the Return-Path:  header which is used as the Bounce address, if errors occur, so you can process them.  You you can not set Return-Path: in mail() headers for some reason... you could before.  Now you have to use the -f option.

If anyone gets this cryptic error message in the PHP error logs:
"sh: -t: command not found"
after upgrading from PHP 5.4, this may be the solution for you.

I upgraded PHP from 5.4 to 5.6 and all our mail() functionality suddenly broke, with no useful error logging.

If this is you, and you've been using ini_set() to set the "sendmail_path" then note that even though it's apparently not mentioned in the upgrade documentation -- or anywhere else I could find on php.net (or a dozen forums) -- you'll now need to go set the sendmail_path in your php.ini file; it is now ignored if you use ini_set() to specify a path to the sendmail binary on the fly.

So, just specify "sendmail_path" in php.ini instead.  That's all there is to it -- that fixed all the mail() functionality for us. 

Hope this little note saves someone else as much time as I spent troubleshooting and researching.  Cheers!

It is worth reiterating that, as stated above, sendmail_path also works for Windows, overriding other Windows SMTP settings.

The comment in php.ini, “For Unix only”, does not make that clear.

This makes it relatively easy to substitute a fake sendmail program or even a shell script/batch file to save mail to a text file.

I use this technique when teaching or testing in PHP.

setting return path:

Return-path header does not work because it is not part of smtp.

on *nix -f may be set on the mail command
some MTAs accept mbox-style "From " header on the first header line
note: no colon after "From" , must be the first header line
or  you may be able to re-configure you MTA to interpret return-path headers

-f is the most reliable method but it may mean that you can't set any other command-line option due to shell escaping problems.

also note that email formatting requirements differ between windows and everything else. sendmail expects only \n line-endings

For linux you can over-ride the default "From" for the outgoing emails by including in php.ini this line:

sendmail_path = "/usr/sbin/sendmail -t -i -f fromMe@blah.com"

The path should work for most linux installations.

You can set on apache2 a "per domain" default address in apache conf VirtualHost section too.

Juste add : php_admin_value sendmail_path "/usr/sbin/sendmail -t -i -fno-reply@php.net -Fno-reply"

change to your own email choice instead no-reply@php.net .

I hope this helps,

On Darwin OS such as OSX (current one: 10.8.3) you need to add a specific command and option to the sendmail_path constant if you have downloaded and installed a mamp with a stack.

Indeed you can see the required libraries for PHP, Apache, MySQL in "common/lib" folder. The problem is when you run an external command using these libraries, for example "sendmail". It could be a problem if it gets the stack libraries and not the system ones (different versions, etc).

The "env -i" command clean the Stack environment variables and run "sendmail" with the system libraries.

Hope this helps.

Despite what this page says about the "SMTP" and "smtp_port" settings being used only under Windows, all Drupal sites use these settings to send email, regardless of which OS they're running in.

Under Windows, I found sendmail_from needed to be a valid email address which has been defined on the mail server being addressed.
