The default debug_peer_level (2) is sufficient, but even (1) is likely enough to log the SMTP conversation (which is all you need here). I set it to 2 for just one known problem sender. I'll see what that tells me. Thanks. > > That seems to be only the debug level for smtpd right? > As documented, debug_peer_list determines which clients have a higher than > default debug level.

Ok. It'd be really handy though! Rob
