PHP: Hypertext Preprocessor

Налаштування під час виконання

На поведінку цих функцій випливають налаштування в php.ini.

**Mail configuration options**
Назва	Початково	Де можна змінювати
mail.add_x_header	"0"	`INI_PERDIR`
mail.log	NULL	`INI_SYSTEM`\|`INI_PERDIR`
mail.force_extra_parameters	NULL	`INI_SYSTEM`\|`INI_PERDIR`
SMTP	"localhost"	`INI_ALL`
smtp_port	"25"	`INI_ALL`
sendmail_from	NULL	`INI_ALL`
sendmail_path	"/usr/sbin/sendmail -t -i"	`INI_SYSTEM`

Докладніша інформація та визначення режимів INI_* на сторінці Де можна встановлювати параметри конфігурації.

Тут є коротке пояснення директив конфігурації.

mail.add_x_header bool

Add X-PHP-Originating-Script that will include UID of the script followed by the filename.

mail.log string

The path to a log file that will log all mail() calls. Log entries include the full path of the script, line number, To address and headers.

mail.force_extra_parameters string

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().

SMTP string

Used under Windows only: host name or IP address of the SMTP server PHP should use for mail sent with the mail() function.

smtp_port int

Used under Windows only: Number of the port to connect to the server specified with the SMTP setting when sending mail with mail(); defaults to 25.

sendmail_from string

Which "From:" mail address should be used in mail sent directly via SMTP (Windows only). This directive also sets the "Return-Path:" header.

sendmail_path string

Where the sendmail program can be found, usually /usr/sbin/sendmail or /usr/lib/sendmail. configure does an honest attempt of locating this one for you and set a default, but if it fails, you can set it here.

Systems not using sendmail should set this directive to the sendmail wrapper/replacement their mail system offers, if any. For example, » Qmail users can normally set it to /var/qmail/bin/sendmail or /var/qmail/bin/qmail-inject.

qmail-inject does not require any option to process mail correctly.

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

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.

The documentation should be made clear that sendmail does NOT default to -t -i when using just /usr/sbin/sendmail. You literally need to specify the options. 

I know this might seem like a no-brainer but I wasted hours trying to get mail() to work only to discover that the sendmail program is NOT passed -t and -i by default as stipulated in the documentation.

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.
