Sorry for the duplicates, I got bitten by a linux-athena
serndmail.cf-ism, that I wasn't expecting.
It is no longer possible to have a local address on an athena
workstation that forwards its mail off the machine. The problem is
that if I set jweiss@tla.mit.edu to forward to jweiss@mit.edu (or even
jweiss@foo.org since all outgoing mail from an athena wirkstation will
go thru outgoing.mit.edu) and someone sends mail with an envelope from
that is not in the mit.edu domain to jweiss@tla.mit.edu, mcs will
bounce it when tla tries to forward it on. (Right now most of these
bounces are probably being lost, because of the problem I reported on
Saturday night, where bounces bounce.)
Additionally, if there are any local aliases on an athena workstation
(eg. postmaster) these will bounce unless owner-foo exists for every
list foo (which makes sendmail re-write the envelope from to
owner-foo).
tritan has already been hit by this problem, tho I don't know if he
lost any mail or not, since some of it was queuing on his machine, and
I didn't examine it to figure out why (though I think he is running a
non-athena-release sendmail binary). I suspect the only reason I
haven't run into the problem is that none of the people on my machine
get mail addressed to the machine very often.
ops, this also affects mail from offsite to things like
postmaster@menelaus.mit.edu.
This is a serious problem and I believe it needs to be addressed by
postmaster@mit.edu.
