Need SPAM filter software more efficient

Post by lowhigh »

Hi everybody!

I'm using Zimbra Free Edition 8.7 with default software: Spamassassin and Amavis. I have follow the instruction in these guide:
https://wiki.zimbra.com/wiki/Anti-spam_Strategies
https://wiki.zimbra.com/wiki/Improving_Anti-spam_system
and i feel quite good.
But few weeks till now, i see that many emails were recveived by MS Outlook 2013 flagged as mail SPM with tag [!!SPAM] which are not identified in Webmail. My boss complain me that why our spam filter don't catch these emails? And I myself realize that these emails actually contain SPAM content but i have no way to automatically discard them although many of them were mark as SPAM in the webmail and I also retrain Spamassassin.

The problem here is content filter seem not effective with Spamassasin. So i need some tool for more
Please offer me some content filter tools/scripts/plugin for Zimbra, i see MagicSpam Plugin but i have no found any detail reviews about this. The filter should applied and charged per server, not charged per user.

Thanks everybody.
