It was a tongue-in-cheek response. By "here" I meant in our company...
The point I was trying to make indirectly, though, was that it has nothing to do with Florida, or any other state, region, etc...just people being different.

In the muddy trenches of the spam war, RFC boot-polishing niceties are irrelevant. Rejection all null senders is clearly a bad idea, but so much spam uses null senders, the temptation is just as clearly present. To catch a large number of spam with MAIL FROM:<>@sender.domain, I sometimes use null sender as a condition to apply other tests: If MAIL FROM:<>, then reject if: no PTR (includes requiring matching A record) HELO hostname not found in DNS helo domain.tld is 2-letter TLD (excluding .us and .ca for N.A. MXs) helo domain.tld is a "subscriber" network domain name. Else, accept (for this test only, more tests to follow) Len _____________________________________________________________________ http://IMGate.MEIway.com : free anti-spam gateway, runs on 1000's of sites To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/ To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
