Off topic: MX entry and ISP

[Suresh_Kumar]

Hi all, I posted a mail sometime back I think it has not reached most of the gusy there was no response from anyone.   How the MX entry and the www entry of a dns server go together when the mail server and the web hosting server are with two different ISPs of different locations. I know they are playing with dns entries but some of my mails get bounced when the receiving smtp server goes for a reverse-lookup. I would be grateful if someone throw their cents in and make me understand.   regards suresh
