Is it possible that some log messages were lost when the log socket got re-created as part of log-rotation? Do your milters always add headers? Or only for spammy messages? Also, you have default_action=accept, perhaps your milters were too busy at the time. When did milter logging cease? When did it resume? What was the message delivery rate during the "gap"... -- Viktor.
