This is where I get confused. I thought if you were using RBL's you would get an X-IMAIL-SPAM-DNSBL header. I have many cases where literally the only spam related header is X-Mail-Filters-DirtyIP. This leads me to believe that IMail is finding the information from some other source. I originally thought that a Dirty-IP flag came because of detected dictionary attacks but I guess that is not the case.

You are always at the mercy of the data provider when using dnsrbls and such. Those who input the data determine what constitutes spam and the spam sources, etc. Sometimes they add entire IP ranges, and this usually causes problems. Dnsrbls and domain rbls are a good line of defense, but both have their faults. Spammers change both domains and IPs as some as they're listed. Ben Tony Priest wrote: > Thanks.
