that's why we don't mix inbound and autobound mail* SA is running on the MX * mail is filtered and clean mail relayed over 100027 to the final server * final server has "-o receive_override_options=no_milters" in master.cf * the bayes is rsynced from the learning machine which is not recommended in general but works in our case because the large amount of HAM including outgoing and internal mail so the final destination which is also the submission server don't scan a second time and MOST IMORTANT there are a ton of rules which needs to be disabled on a submission server, SPF is your smallest problem, DNSBL like PBL or DUL (sorbs) are in short: a submission server needs a complete different SA config
attached a "local.cf" from the submission server tuned for a milter-reject of 8.0 points and at the bottom are a lot of meta rules disabled or scores overwritten (parts of the scores are shared with the MX)
over the last 3 months one false positive and two succesful dictionary attacks killed (the spammer did not realize he had the correct password and was rejected because the mail-body and continued the dictionary attack)
