[email protected] [2/7/2004 4:55 PM] : this may be deemed off topic - if so apologies in advance. however i respect many of the opinions i see here so thought i would take a chance and ask.Having proper rDNS is a good thing, strongly recommended but definitely not required for sending mail. There are quite a few sites (including the freebsd.org mailserver, and, on a case by case basis, even AOL) that do refuse mail from IPs without rDNS, but turning on a "must have rDNS or you can't email us" setting will definitely result in a non trivial amount of false positives. -- srs (postmaster|suresh)@outblaze.com // gpg : EDEDEFB9 manager, outblaze.com security and antispam operations
