Forum HELP! No emails being sent after upgrade
 

I've got the same problem as this guy:

http://www.vbulletin.com/forum/showt...ed#post1984825

This is completely a vbulletin issue as users who are subscribed or have threads which they have subscriptions are not receiving emails.

In addition, new users aren't even receiving emails after signing up. I'm wondering if others have this problem or encountered it. I tried switching off smtp and turning on sendmail instead, neither works. Not good at all...
