Hello-
I just installed cpg1.3.2, and I edited the include/mailer.inc.php to contain my mail server and login info. I can send ecards just fine. However, users registering get an error about the email being able to get sent. If I turn on debugging for Everyone and notices as well, I get this when trying to register:
Ran into problems sending Mail. Response: 550 Administrative prohibition

 That account has since been deleted, but, any ideas? Users can't get any registration info.
 I figured if that wasn't working, the ecards wouldn't, either, but that works fine.
