I have seen this error (warning?) message pop up in the header when I approve someone.

Code
 SMTP server response: 550 <[email protected]> No such user here in c:\Inetpub\wwwroot\SomeWebsite\Forums\ubbt.inc.php on line 293


I have also found out the users are not getting emails. I am getting emails, but my account is "local" to the SMTP server and accepts mails "to" me.

At least this is what I am thinking. I can get mail as either the admin or as a user and they have different email addresses, but they are "local" to me. The other users are not.

Any ideas?
