	I ran a mixed POP-before-SMTP and SMTP-AUTH system for some
time (started with PbS before S-A was available for the majority of
the MUAs I had to serve) and thus had to solve that very conundrum.
I'm pretty sure my solution found its way to this list, so it might be
worth trawling for.

	If your PbS algorithm uses a sendmail map (e.g. access.db)
then it ought to be fairly easy to pull it into MIMEDefang and
incorporate it into an auth check.

	Of course, if you're trying to do it all in sendmail before
incurring the hit of an MD thread, then it gets a little less
straightforward. (But doable -- I had PbS and S-A working in
sendmail.cf before we added MIMEDefang. MD just made it lots lots
easier -- I'll take perl over sendmail.cf any day. :-)

	Cheers,
