Athena MX record change problems, part 5
This is more of a "duh" than a bug, but it caught me by surprise and
lost some mail for me, so I figured I'd warn other people about it.
MAil coming from "local" accounts (by default this is root, daemon,
and MAILER-DAEMON) from off-campus (eg., mediaone) hosts that is
delivered thru outgoing (8.3 suns/sgis with the default sendmail.cf,
8.2 netbsd machines with the default sendmail.cf, and 8.2 linux
machines using the default or outgoing sendmail.cf) will bounce,
because the envelope from doesn't meet outgoing's criteria. One
work-around is not to have any local accounts by removing everythign
from class E in your cf file. Another workaround is to point your
mailer at mit.edu rahter than athena, but I have no idea how long that
will work (I think postmaster is planning to do somethign to the
machiens handling mail to mit.edu soon, but I don't know what.
