Best content-filter setup (spam-filter)
I'm very interested in what content-filters people use with large amount of emails.
Lets say I have 1000 mailboxes that needs to be checked for spam, what would be the ultimate setup for this?
The only thing I would require is to append [SPAM] to the subject if it's a positive and some whitelist/blacklist per domain.
Right now I'm running Maiamailguard with Postifx and to be honest Maia doesn't work very well and I want to change the entire content-filter setup to something more efficient.
