We have installed Zimbra 8.0.4_GA_5737 (build 20130524120036) almost a month ago and have been working with internal IT types and tech support from Zimbra but nothing has helped! In the last 12 hours I have marked 427 e-mails as spam from my inbox, during the same time the anti-spam program found an additional 27 spam e-mails. This has been going on for weeks and weeks- either the system is stupid and can not learn or it simply is not a program we should continue to use. Any and all help is welcome!
