Email Notifications Out of Control

Since day 1 we could never get email notifications for Zenworks to work and we always thought it was something to do with the email servers we're forced to use (we can't control them). So we've ignored it. However, yesterday, they magically started to work........a little too well. In a 12-hour period we have received over 12,000 emails with Error reports and whatnot dating back to October. Can't get it to stop. I read that there's an EmailQueue table in the database, but I can't find it in the Sybase Database. I'm using 11.2.3a. Any ideas?

Thanks
