I agree thousand are running secure and compliant servers but millions are
not adhering to the standards. Just look at the list of known open relays
mail servers on the net in any major blacklist. These have been used by
spammers and yet they are still open relays.
With spam now accounting for 80% of all email traffic we are fast
approaching email as a useless communication system. I have already set my
mail client to require a return receipt so that I know my email was not
caught in a spam filter.
Email and % spam have reached a crises level that is why spf is taking hold.
I am just looking for ways to require responsibility and identification of
violators. Reverse dns is an RFC yet there are millions of mailservers that
do not have proper reverse dns. We have tested reverse dns blocking by
filtering all email received from an IP address without the proper reverse
dns and found that 70 plus percent of spam can be blocked this way.
Unfortunately it also block 20% plus valid email servers.

Standards of behavior, yes... but not of finance.
Thousands are running perfectly secure and compliant servers who could
not afford to buy any sort of license... nor should they have to --
after all, there are people out there acting legitimately who would be
tortured if found by their governments...
