One thing that often goes unsaid, and is therefore often misunderstood, is
that 'reverse' and 'forward' domains are not the same, so having authority for
a 'forward' domain does not automatically give you authority for some
corresponding 'reverse' domain. There's not really any sort of one-to-one
correspondence to begin with. All 'reverse' domains are sub-domains of the
in-addr.arpa. domain and they are generally delegated by and to whoever
controls the specific IP numbers. In your case, that's your ISP. If you wanted
to control DNS for your reverse domain, you'd need to have your ISP delegate
it to you. Since you only have one IP address, though, it's probably not worth
the trouble -- you just need to make sure that one PTR record points to the
right host name.

That's pretty much what I was getting at (about the reverse records), even if
I didn't say it explicitly. Which side of your firewall are the problem
machines on? If they're on the inside and trying to use your QDNS server to do
the reverse resolution, that might be part of the problem (I'm just guessing
now, don't give too much weight to the suggestion).

Yes, DNS related problems with mail can be a bear. 8^)
