I don't see how this is true. I ran a mailserver just fine for half a
year on a Rogers connection, and had no problems sending to/from UBC, SFU,
and a bunch of other domains which I'd expect to have properly configured
mailservers. I had a .dhs.org subdomain set up, and had my computer
configured as thud.dhs.org. Mail to/from it went fine. Besides, if, as
you say, every properly configured mailserver will do a lookup for the FQD
of the machine, that would mean that everybody who owns their own domain
but piggybacks it on a Rogers or ADSL connection would be out of luck,
since reverse IP lookup would return their Rogers/ADSL host. If it's not
a reverse lookup that's done, but a normal hostname->IP one, then the easy
solution I guess would be to set up a DHS redirector, and configure it so
that the MX record points to the same computer. That's how I did it,
anyways, so your mileage may vary.
In case it might be important... while with Rogers, I used thud.dhs.org as
a host and sent/received mail fine. I'm at UBC now, hooked up with the
campus RADSL service (not ResNet). I have my own domain, and I'm running
a DNS server that's authoritative over that domain, also. I've configured
reverse lookups to fail on my dns server, because UBC's servers are set up
to be authoritative over that IP range, and I don't want dns conflicts
developing.
