[NMLUG] Reverse DNS

[jmdelapp at delapp.com (Mars DeLapp)]

My email service provider has started blocking email that fails a reverse DNS lookup. This has caused me a great deal of 
grief with rejecting a high percentage of legitimate email.

I have been working on setting up my own email and web server and wanted to make sure I got it right before moving my 
business web site and email to my server. Looks like I now need to accelerate my work and get my business email moved ASAP.

I am using Postfix. What is the right way to do reverse DNS checks on email?
