About a week ago Mark sent a piece of mail
(http://diswww.mit.edu/menelaus/cfyi/14125) detailing a change to the
email system infrastructure. The purpose of the change was to force
authenticated mail and unauthenticated mail to have completely
different machines in the received lines, right down to the outgoing
machine that initially picked up the mail. This was prompted by some
anti-spam lists putting MITs outgoing mailers on their list of bad
machines due to some of the unauthernticated mail that went through.
Unfortunately, the nature of the implementation was such that machines
that honor MX records have their mail delivered through the
unauthenticated outgoing path (outgoing-legacy.mit.edu).
I sent mail to network at the time (case 667132) for those of you with
casetracker access. Based on a report I heard from the mail system
infrastructure presentation that was this morning, It appears that
Mark believed that this issue had been brought to release-team though
I hadn't gotten to that step yet.
Anyhow, I wanted to confirm that we are interested in making the
change, assuming that it can be done with a simple change to the MX
records for athena and does not require a change to all athena
workstsions as Mark originally suggested. As far as I know the only
down side will be that it will no longer be possible to look at the
workstations logs and tell which of mmc and mcs actually handeled the
message. If anyone has any problems moving forward, please drop a
note. If I don't see anything negative in a day or two, I'll ask Mark
to move forward.
