MessageSure, but since I'm not an open relay at this point it doesn't have 
anything to do with my current problem, which is that mail sent to may domain 
bounces with a 5.3.5 error.

  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:

  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.
