After a new user is registered, when they click the activation link from their email, CB starts to send out emails to ALL registered members notifying them of the new user registration. We have hundreds of members, so this overloads my mail server and causes it to fail.
If i turn off the setting for moderator notification emails in CB Configuration -> Moderation, the problem is solved. It seems like there is a bug somewhere in the CB notification system, but I'm not sure why this would be happening. Any one have any suggestions?
