Using the same resolver as the SIMS box is pointed to, I see:

<nslookup:opt20.edirectnetwork.net/A>
Non-authoritative answer:
opt20.edirectnetwork.net A 198.139.238.246

<nslookup:246.238.139.198.in-addr.arpa/*>
Non-authoritative answer:
246.238.139.198.in-addr.arpa PTR u-198-139-238-246.classichosting.net

<nslookup:u-198-139-238-246.classichosting.net/A>
Authoritative answer:
   Name Error - domain name referenced does not exist.


I'm not concerned about the A and PTR not matching up or the A record 
not existing - these are pretty standard fare - but how does SIMS 
figure certain things out?

I assume it starts with the HELO and looks up that domain name. If 
the HELO is "correct" and all is copasetic, it is "verified" and 
we're done.

If the HELO is not "real," SIMS still has an IP with which to do a 
reverse lookup. Does it do this reverse lookup and try to resolve the 
matter further, or does it always just stop there and place the IP 
and HELO in the header?
