I think that transport map should be ok. Implement the 587 smtpd in master.cf as shown above (I corrected the recipient restrictions per Mikael's reminder) and have your client MUA submit to TCP 587, and you should be good to go. If not, let us know. It appears your content filters are what are tripping you up here. Using a separate submission smtpd which bypasses the content filters should fix the problem. -- Stan
