Hi Thomas,
Thanks for the lead. There really wasn't anything very relevant arising
from a straight forward search for "SMTP Relay" (with or without quotes),
however, following a long rabbit trail of links that started in a
tangentially relevant article, I was able to locate a document with very
relevant content about a third of the way through:
www.isaserver.org/img/upl/exchangekit/2003messagescreenerintrelay/2003messag
escreenerintrelay.doc
One must add the domains you want to restrict receiving to, to the Domains
node beneath the virtual SMTP server. I had been slogging through the
properties of the service itself, and what is done with the domains is not
clear from the UI or the help. Apparently, only the remote domains listed
accept incoming mail, but if you have no remote domains, it accepts all
comers. Strange design.
Now that I've done this, and allowed anonymous connection, I can receive
bounces, and I am not an open relay (not strictly -- any mail is accepted by
the service, but nothing is actually forwarded for delivery unless it's
addressed to my domain). However, any mails sent outright to my domain
bounce with an SMTP 5.3.5 config error, which is some kind of loop back
problem. Anyone have insight into that? Again, extensive Googling is not
getting to the heart of this. I only have one virtual SMTP server, and no
connectors to Exchange or anything else.
Best,
--Bob

I have a W2K box that runs just the SMTP service. It's used to send out
emails to a couple thousand subscribers to our reminder service a couple of
times a month. These are emails put into the SMTP server's queue by a
custom application that generates them. We don't actually use Exchange or
anything else on this box, it's just a stand-alone unit isolated from our
corporate network for safety's sake.
I'm a bit of an email administration virgin, so forgive me if this is a
naive question ... but if I uncheck the box in the SMTP service that allows
anonymous logins, so that I'm not an open relay -- then any mail that gets
sent to that box gets bounced. How do I allow emails to my own domain in,
from all comers, without being an open relay? I want to catch repy-to's and
bounces of the mails I'm sending.
The bounce error says, "relay refused" but that wouldn't be a relay, it'd be
a delivery.
I've Googled around but can't find anything that addresses my scenario.
