There is an MX for innerprise.net that points to mx1.innerprise.net.
However, there is no A or CNAME record for mx1.innerprise.net, which makes
it kinda hard to use. ;-] This is a problem with innerprise.net's DNS
that they should fix.

Exchange is probably falling back to the A record for innerprise.net, which
does have an MTA that answers on port 25. SIMS is obviously not trying it,
presumably because there is an MX record. Someone with better knowledge of
the RFCs can tell us which is the correct behavior.
