Mediawiki E-Mail

Can't Send Out Confirmation E-mails (using SMTP)

(confirmed on Slackware 10.2 & Mediawiki 1.7.x)
To use SMTP on Mediawiki 1.5+ you must add:

$wgSMTP = array(
         'host'     => "your.smtp.server",
         'IDHost'   => "your domain or blank",
         'port'     => 25,
         'auth'     => true (or false), 
         'username' => "username (if auth=true)",
         'password' => "password (if auth=true)"
         );

...somewhere into LocalSettings.php (found in the Mediawiki's root directory).

After adding the above to your LocalSettings.php file, the SMTP service still probably will not work. If you examine your /var/log/apache/error_log file, it probably will have this error:

[error] PHP Warning: usermailer(Mail.php): failed to open stream: No such file or directory in /home/joebleau/public_html/wiki/includes/UserMailer.php on line 82

For some reason, the Wiki's config script screws up the path to the PHP's PEAR extensions. To fix this, edit the LocalSettings.php line that says:

$path = array( $IP, "$IP/includes", "$IP/languages");

to say:

$path = array( $IP, "$IP/includes", "$IP/languages", "/usr/lib/php" );

After that, your smtp outgoing mail should work for your Mediawiki installation.
