Thread:Project:Support desk/Using $wgSMTP with Godaddy email account/reply (3)

I believe 'username' is only for the username used during authentication. I don't think it has anything to do with the from address used on emails (With that said, your username could very well be whatever the from address is, so that may be the correct thing for it).

Normally $wgPasswordSender would be what controls the from address, not anything to do with the SMTP config. So yes you would need to set that appropriately.

Usually the thing sending mail via SMTP will identify itself in the HELO command. This is usually not related to who the email is listed as being "from", but if you really want to, you can add a 'localhost' key to the $wgSMTP array to control that: $wgSMTP = array( 'host'    => "secureserver.net", 'IDHost'   => "server.sturmkrieg.com", 'localhost' => "server.strumkrieg.com", // rest of the stuff you had above.
