I'm not sure if being on Windows affect mail settings.
Anyway I'm using Windows and these are my settings:
$wgEnableEmail = true; $wgEnableUserEmail = true; $wgEmergencyContact = "Company name admin@company.com"; $wgPasswordSender = $wgEmergencyContact; $wgSMTP = array( 'host' => "mail.company.com", 'IDHost' => "company.com", 'port' => 25, 'auth' => false, 'username' => "mailusername", 'password' => "mailuserpassword" ); $wgEmailAuthentication = true;
