For further details and definition of the PHP_INI_* constants see ini_set().

Here is a short explanation of the configuration directives.

SMTP string

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

SMTP 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. Only available since PHP 4.3.0.

sendmail_from string

Which "From:" mail address should be used in mail sent from PHP under Windows.

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.
