I'm fairly new at zimbra and have been trying to address our SPAM issues.
I've been reading through the various threads on the SPAM trainer, and one of the issues that needed to be corrected was that no junk mail was being logged to the SPAM trainer accounts. I corrected that by correcting the account that they were pointing to using:
zmprov mcf zimbraSpamIsNotSpam account
zmprov mcf zimbraSpamIsSpam account
However, since the SPAM trainer accounts have been activated, more emails are passing through.
The Kill Percent is set at 40 and the Tag percent is set to 20. I've setup RBLs and they don't seem to have any effect. Any help would be appreciated.
