Popfile as spam-preprocessor to Zimbra?
I'm looking for an alternative to the default spam handling on Zimbra. Too much messages keeps getting through.
Before I switched to Zimbra, I used Popfile as spamfilter. It was very powerful and I remember abandoning it as a minus to the decision to go Zimbra.
While it is originally a pop client (hence the name), SMTP support was added around the time I went to zimbra, but I haven't used that one.
Does anyone here use popfile and recommend it with zimbra ?
