Hmmm, should I dance around like a god?  or do they even dance?  :-)
I have to disagree with you John.  It is standard practice to require a
valid RDNS lookup in order to except a piece of mail.  Basically all you
are doing is verifying that the sender is in fact who they say they are,
or should I say the server connecting to your server is who it is
advertising itself as.  As you say, take a look at the real world:
A guy walks into your mailroom wearing a purple shirt with a unibomber
emblem and says "Take this package, it's from UPS..."  What's your mail
clerk going to say?  "I'll take it because I don't care who you are, I
just take all packages addressed to me..."?  I hope not, that's how
things get blown up, that's how your email system will get blown up with
viruses, spam, threats, etc...  If you cannot verify the origin of a
piece of mail and you except it anyways, you put yourself at risk, a
conscience email administrator is not going to allow that.

Andrew, please tell me you are not actually considering doing this.


Yes, the big want-to-be Internet God's such as America Off Line
block/refuse on no PTR, but that is not practical in the real world as
the rest of us know it. Besides, I think America Off Line is just trying
to get on Dan Quails' good side, if he has one.

Is there anyway to get IMF to drop emails that fail reverse lookup?
