I am seeing the following error messages when someone on the local domain
(darwin.nmmnh-abq.mus.nm.us) tries to post a message to a list at
listserv.nmmnh-abq.mus.nm.us.  Darwin (198.59.157.5) is running exchange and
stamps all outgoing mail with a return e-mail address of
[log in to unmask]  Listserv (198.59.157.8) is running the
current versions of Listserv and LSMTP.

The problem seems to be internal, people from outside the IP block seem to
be able to post to lists at the Listserv site with no problem.

Any ideas or suggestions would be appreciated.

Thanks

John Chadwick
listserv manager at listserv.nmmnh-abq.mus.nm.us (usual address is
[log in to unmask]).
