Users not recieving emails

[Dan]

Originally we had several of our users not being able to recieve emails from the forums for activation and subscription notifactions (me included). So I thought it might have been something with how vBulletin sends mail through php. So I changed it to smtp. Now no one recieves emails. When doing a test in the admincp I get the following.

The following errors were outputted by PHP when attempting to send mail:

Warning: Unexpected response from SMTP server during TO address transmission in /includes/class_mail.php on line 519

Any ideas?

Switch back to normal mail handling and focus on resolving that.

Yes but I don't want to mess with my ISP, last time i tried getting them to unblock my domain they never did it.
