Excuse me for double post, got database error on submit for first time.
I wanted to get info on best practices, how to deal with multiple Zimbra MTAs concerning Spam training. As to manual and release notes, only first MTA server is marked as zmtrainsa_cleanup_host=true. The others - false.
When a spam training script is run, messages from spam/ham training accounts are deleted. The problem here raises, if I use several Zimbra MTA servers. As far as I understand, is that, if first and only one MTA is marked for training spam, the other servers do not get any possibilities to train them, even if I mark it True via zmlocalconfig, because spam/ham mailboxes are purged.
What would be the best way to handle these spam trainings on multiple MTA Zimbra servers serving as a mail exchangers for multiple domains? I am concerned about the load of only one Zimbra MTA server, and thus would like to balance it between several.
Additional question - does on ZCS 6 and 7 (OpenSource) Spam training (user managed) is by domain, exact email account or per server? E.g., if email@example.com marks exact mail as a spam, but firstname.lastname@example.org the same mail marks as ham, or just leaves it in inbox without marking, how does spam training will influence this?
