Thanks for your reply.  Maybe you can tell me if I am going to get into
trouble with this - but - since I host and route all of the domains, I gave
SIMS the domain that I want replies to go out with.  I tested it and it
worked.  Since I don't understand SIMS fully yet - must it have the domain
name of the machine it is on or will a CNAME work for DNS routing?

The SIMS main domain name is not checked by SIMS against DNS at all. It is what SIMS considers as its own identity. For it to work, the name should be one for which mail will eventually go to that machine. That can be a name that only has an MX record pointing at the SIMS machine, it can be a name with an A record pointing at the machine, or if you really want it can be a name that only has a CNAME record that maps it to a name with an A record for that machine.  I'd avoid the CNAME because I see them as a generally bad idea (I know of exactly one good use for them, and it is rather arcane) but you can use it if you really want to.

and on this:

BTW - Bill,

I did use a acgi script from my web server and it must have written the auto
reply because I didn't do it.  I thought the script would send an e-mail
addressed properly from the server, but it looks like it wrote an auto reply
to the SIMS folder - which in turn is doing what you and chris explained.

Oh. I had assumed that you used the SIMS built-in autoresponder.

Maybe changing the script could make the mail look right. Whatever composed the mail wrote any "From" or "Reply-To" headers the mail has. SIMS does not modify headers, it just adds a Received header documenting the transit. If that script even uses SIMS (it may not) then SIMS just took what the script gave it.
