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, Ole -- Ole Craig * UNIX, linux, SMTP-fu; news, web; SGI martyr * admin-at-large Need a seasoned *NIX admin in the Denver/Boulder area?
