Wish I could say we are having the same results. We are actually having more reports of spam after getting on v11. I put a call into support yesterday and we reset the Bayes database and even enabled tarpitting but nothing seems to get better. I guess we will be providing more examples to support to see what we can do.
Our DNSBL queries are 100% and we hit the 200 spam/ham within 2 hours or so of reseting.
Darn SPAM!
