But what could be writing an 8K line to RESULTS?

Certain custom rulesets for SpamAssassin will result in triggering *lots* of rules.


Mainly, this is the Tripwire ruleset, which looks for unusual letter combinations and assigns a low score to each, the idea being that if something has just a few, like an alphanumeric confirmation number, it won't cause a false positive, but if it has a lot, it will trigger many of these rules and result in a big boost to the spam score. If you're adding the spam report to the headers, a lot of its on tripwire can easily stretch that report past 8K.

What I do is have MD check length($report) and reject/quarantine the message if it's too long. Another approach would be to try to collapse all the TW_ lines in the report into a single line. A longer-term solution would be to rewrite Tripwire using count-based meta rules so that only a few rules will actually be visible in the report. (At the time it was written, that capability wasn't available.)
