I have a little wiki set up on a home server that is connected to a typical consumer ISP account. Lots of smtp servers reject mail that comes straight from this server, so I usually set things up to mail through another smtp server I have smtp-auth access to.

I found this page:

http://mail.wikipedia.org/pipermail/mediawiki-cvs/2004-February/000414.html

which explains that I can set up $wgSMTP as an array, like so:

$wgSMTP = array ( "host" => "smtp.wherever.com", "IDHost" => "mail.wikipedia.org", "port" => "25", "auth" => true, "username" => "mailID", "password" => "mailPswd");

(example only; I used real values for my setup) and then UserMailer.php should send via the server that I specify.

Wherever I set $wgSMTP (I tried LocalSettings.php, DefaultSettings.php, and in the function itself in UserMail.php--I realize they should all have the same effect and that LocalSettings is preferred), mail seems to break. For example, when I try to mail myself my password on the login/create account page, I just get a blank page (after clicking the "mail me a new password" button) and no mail ever arrives.

Any thoughts? Where can I look for errors, etc., or how else can I test easily?

Thanks, Matt
