includes/DefaultSettings.php has two different defaults for $wgPasswordSender: a) (line 520 in 1.16): /** * Password reminder email address * The address we should use as sender when a user is requesting his password * Default to apache@SERVER_NAME */ $wgPasswordSender = 'MediaWiki Mail <apache@' . $wgServerName . '>'; Note: this was changed in SVN trunk r76234 to: $wgPasswordSender = 'apache@' . $serverName; b) (line 1720 in 1.16): /** For email notification on page changes */ $wgPasswordSender = $wgEmergencyContact; This is highly confusing for people who read DefaultSettings.php. Even http://www.mediawiki.org/wiki/Manual:$wgPasswordSender has a section saying so ;-) Please remove the first setting (it's always overriddenAFAIK) to remove that confusion. Bonus points if you move the second/remaining one near the definition of $wgEmergencyContact so that it's easyer to see what the actual default value is ;-)
Already fixed in r76234.
