Chuq's articles reminded me of a growing problem we are having with uucp mail and sites running the MMDF mailer. Chuq's sendsys article arrived here with this path: > Path: gatech!nsc!chuqui@nsc.UUCP And gatech (being on CSNET) is running MMDF (version 1 I think), and it returned the sys file mail with this semi-nasty message: > From gatech!mmdf Mon Nov 19 15:11:24 1984 > To: msdc!news > Cc: postmaster > Subject: Illegal Address (nsc!chuqui@nsc.UUCP) > > Your letter has been intercepted trying to access > a restricted access host (e.g. an ARPANET host). A copy > of your letter has been sent to the system administrators. > The text of your letter follows. > > --------------- Returned Mail Follows -------------- > >From news Mon Nov 19 14:23:26 1984 remote from msdc > To: gatech!nsc!chuqui@nsc.UUCP > . > . > . > --------------- End of Returned Mail --------------- It seems that MMDF does not know about the UUCP domain or it just checks for the "@" and thinks that it is destined for the ARPA domain. With the growing number of sites running MMDF, it is getting very difficult to get uucp mail to follow a return path to an ARPAnet site. Does anybody know if MMDF version 2 fixes this problem?

I don't think that's the real problem: it's not that MMDF saw the @ and said, "aha, ARPA host", it's that it couldn't find a route to nsc.UUCP. The check is done by a substitute /bin/rmail, and it has a permission check that says something like this: if source host is in "senders.ok" then OK else if destination host is in "uucp.hosts" then OK else error It does NOT actually check for ARPA hosts! Back when we were running MMDF 1 under 4.1, if someone sent mail through us to ``foovax!bar'', where we'd never heard of foovax, they'd get that nasty-looking note. I don't think MMDF II has anything better.... -- (This line accidently left nonblank.)

MMDF II is much better. Much has been done to the UUCP channel. -Doug-
