Actually, the messages I originated to the Mandrake mailing list used to get dumped into the bitbucket somewhere along the chain when I was originating mail without a valid MX record matched to my domain name. I simply don't see that as a problem since dyndns.org offers free domain names, dynamic dns and allows you to specify an MX record, all with dynamic ip addresses and you don't even have to pay for it. Failure to have a valid MX record for reverse dns is simply laziness on the originating server's end and if they get mail rejected because of it, they only have themselves to blame. > I could be wrong, since I don't handle huge volumes of mail, just personal > correspondence, but in that, I have had no problems. Some admins also reject mail from any IP range that is specified by the ISP as dynamically assigned. I also never had mail messages rejected for that but have heard of others who did. All depends on how strict the mail admin is about who he accepts packets from. -- Bryan Phinney Software Test Engineer
