Manual:$wgSMTP

Details
For using a direct (authenticated) SMTP server connection, you need to fill an array with details about your connection. Set to false (the default value) to use the built-in PHP mail function.

For example:

'IDHost' is a MediaWiki-specific setting used to build the Message-ID email header (see RFC 2822, sec 3.6.4 for more information on a properly formatted Message-ID). For the remaining settings, see Mail::factory for a more complete description. (Scroll down to the  parameter.)

This setting requires PEAR's Mail package to be installed (run, and you can run "pear list" to confirm). If you get an error message stating that pear is not installed, then install  and then try again.
