    configuration setting may be set

    Here’s a short explanation of the configuration

    mail.add_x_header bool

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


    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

    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(), even in safe mode.

    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.


    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 from PHP under Windows. 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

    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_port and
    are ignored and the specified command is executed.
