RE: FP Pattern for sbl-xbl.spamhaus.org
For a while now, my philosophy has been to use sbl-xbl.spamhaus.org to block at the connection level and not even allow these messages onto my server. Much of the remaining spam filtering is then done by SURBL-checking. However, more recently, I been testing samples of sbl-xbl.spamhaus.org blocked messages and I've noticed two things.
(1) more false positives than I would want to see (though still a very tiny, tiny percentage overall) get blocked by sbl-xbl.spamhaus.org
Have you checked if those false positives are in SBL or if they are in XBL?
