It does not appear to be SIMS having the problem. The SMTP session is with and it looks like that machine is whining.

I do see that at least the Sam Spade site ( is
getting a weird answer for the MX records: ttl=0 seconds. If you had such
records in the DNS at some point and did not update the serial number in
the SOA record upon a change, this could confuse some sites.

Unfortunately, I can't get the same answer from any resolver where I can
see more than Sam Spade gives me.  I would certainly suggest that you bump
the serial number on the zone to assure that this is not the problem, as
that's the only thing I can think of that might cause this.
