Dovecot already knows about the ID fields a client sends. It just doesn't log them by default. This default, of course, can be changed - by setting imap_id_log appropriately. For example imap_id_log = * will log all ID info a client sends. Obviously, if a client doesn't send ID info, there's nothing dovecot can do about it, though. -- Regards mks
