XLIX. Mail functions

Introduction

   The mail() function allows you to send mail.

Requirements

   For the Mail functions to be available, PHP must have access to the
   sendmail binary on your system during compile time. If you use another
   mail program, such as qmail or postfix, be sure to use the appropriate
   sendmail wrappers that come with them. PHP will first look for
   sendmail in your PATH, and then in the following:
   /usr/bin:/usr/sbin:/usr/etc:/etc:/usr/ucblib:/usr/lib. It's highly
   recommended to have sendmail available from your PATH. Also, the user
   that compiled PHP must have permission to access the sendmail binary.

Installation

   There is no installation needed to use these functions; they are part
   of the PHP core.

Runtime Configuration

   The behaviour of these functions is affected by settings in php.ini.

   Table 1. Mail configuration options
   Name          Default               Changeable
   SMTP          "localhost"           PHP_INI_ALL
   smtp_port     "25"                  PHP_INI_ALL
   sendmail_from NULL                  PHP_INI_ALL
   sendmail_path DEFAULT_SENDMAIL_PATH PHP_INI_SYSTEM
   For further details and definition of the PHP_INI_* constants see
   ini_set().

   Here's 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_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. 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.
