Adding SMTP support in MediaWiki

gistfile1.txt

Add the following to LocalSettings.php

$wgSMTP = array(
                'host'     => 'smtp.gmail.com',
                'IDHost'   => "wikibiz.vn",
                'port'     => 587,
                'auth'     => true,
                'username' => [email protected]
                'password' => "mypassword"
                );
                
$wgEnableEmail = true;

Then you install PEAR packages:
pear install MAIL Net_SMTP
