I am running spamc in a mail filter. I have it add headers with test scores. For REALLY spammy spam it adds so many lines (or maybe its one really long line) that it causes the 534. I am running my MX servers and my IMAP server on separate machines so after spam filtering on the MX server it resubmits the message to go to the IMAP machine. Whether or not the 534 is causing the 556 I should probably figure out how to limit the size of the added headers.
