Hi,<br />
You got to set it up externally. <br />
Ask your ISP to set it up for you. Goto <a href="http://www.mxtoolbox.com" rel="ugc">www.mxtoolbox.com</a> and verify RDNS for your domain<br />
Thanks<br />

Sorry, i was not descriptive enough. &nbsp;I am getting spam. &nbsp;Even tho I set reverse DNS lookup on my exchange server- &nbsp;so that if reverse DNS does not resolve an incoming message will be considered spam - I am still getting spam. &nbsp;I look in the message header of a spam that came thru and it says reverse DNS failed..so why didnt my exchange block it??

Exch 2k3 - reverse DNS is set in SYS manager so why am I still getting emails that reverse DNS fails?
