I think this might be Ole's point.  That the "real" SMTP server
already has code to validate local recipients as well as many other
such checks.  Perhaps tmda-ofmipd should just pass the message on to
the SMTP server, and when the SMTP server barfs, tmda-ofmipd will
notice that, raise an exception, and the user's MUA will halt
processing.  This is how tmda-ofmipd has worked since the beginning.
I wonder if the code you recently added is really necessary?  Tbird
aside, I know most MUAs handled things correctly, since I tested about
a dozen of the most popular ones at the time.  It's just been so long
the particulars are a bit lost on me.
