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.
