In this day and age of rampant spam and viri and smut and all manners of malicious activity, it is absolutely necessary that we keep our own servers/systems/networks/email clean with all I's dotted and all T's crossed so as to not add to the problems.
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.

Subject: [ExchangeList] Reverse DNS Look-up and Mail
Just a question. How many folks out there have reverse DNS lookup set-up for their domains to support mail?
