I would like to hear from folks who feel they have understand how
sendmail works.  I have a couple of different needs/wants for
use of context in the address rewriting rules.  By "context", I mean
that the recipient address depends on the senders address.

1) Policy around here is that there should be two classes of users:
those that have access to off campus resources and those that don't.
In terms of mail, this means that the class B users should be able
to send mail to anyone on campus but should not be able to send mail
to off-campus sites.  It is not clear what should be done with mail
from off-campus to a class B user, but I suspect my superiors would
like to discourage that as well.

2) For the ease of identifying a message as local (and therefore
probably of higher priority), I would like to internal mail to have
no domain part (i.e., "user" instead of "user at vuse.vanderbilt.edu")
*BUT* I would like mail from mailing lists that happens to originate
locally to be treated as external mail and keep the domain part intact.

Can these (probably irrational) criteria be met with sendmail, and if so,
how?

Please reply directly to me, and if there is sufficient interest, I will
post a summary.
