Basically, your problem is spam... a misguided attempt to filter out unsolicited mail, a number
of people have started using MTAs which throw all the relevant
RFCs out of the window and block incoming mail on new and exciting
criteria, such as 'can I reverse lookup the name of the sending MTA.'

Basically, you have three options...

  1. Whenever you find such a site, complain bitterly to their
     postmaster about the general cretinousness of running a non-RFC
     compliant mail server.  Point out that having dynamic IP and/or
     sending mail direct from a machine without a DNS entry doesn't
     make you a spammer any more than being Italian makes you a Mafia

  2. Decide that people using such cretinous systems aren't worth
     mailing anyway.

  3. Route all your mail through your ISPs smarthost.

1 will give a certain amount of satisfaction, but probably won't help.
2 would be fine except usually the person on the end of the broken
MTA probably isn't the one making the stupid decisions.
3 may well offend the sensibilities, but is probably the only
solution.  Unfortunately.

This is a remarkably similar problem to that just introduced by some
idiotic web sites (most notably Sun's,) which won't let you download
anything unless they can reverse-lookup your IP addy (so they can
try and determine your country & thereby enforce export restrictions.)
