I am a hosting provider sir and both my server and my clients DNS records
are all properly configured and there is no problem whatsoever.
Your statement is proven false.

Hi,
A rDNS is certainly important but I dread the day when RBLs start requiring
MATCHING rDNS. That would be a b-i-g problem for mailservers legitimately
hosting email for multiple independent domains. It is generally not
possible to force an email server to send out emails from one virtual
multi-homed IP or another, as that part is generally controlled by the
TCP/IP stack in the operating system. (Virtual multi-homed IPs not to be
confused with dynamic IPs).
Best regards
JW

So yes, you HAVE to have proper MATCHING reverse DNS records set up for any
IP address that is involved in the transmission of email.

Just a question. How many folks out there have reverse DNS lookup set-up
for their domains to support mail?
