This is what I thought. The SMTP_FORWARD originally was set to mail.uu.net
(our ISP), and it worked without incident for a long time. Then things
went kerblooioe. Coincidentally or not, this happened around the same time
I made some routing config changes to our Exchange server, but I never
dreamed that would affect the Listserv box, which I thought was not
interacting with the Exchange server at all.
If there was a problem with UUNet (and they insist there's not), I've
worked around it by now running Listserv through our Exchange server and
then straight to the net (after numerous trial-and-error routing
configuration tweaks). I *just now* got things going again.
Thanks,
Tracey
