Hi guys,

this might be a little offtopic, but i'm having some issues with my mail 
on my webserver....

i can't seem to send to addresses that require reverse lookups, namely 

host mxi1s.craigslist.org []: 554 <unknown[]>:
    Client host rejected: rDNS/DNS validation failed. Please setup matching DNS and rDNS records:

how do i set up dns and matching rdns records?

i have cpanel and am on RH enterprise if it matters.
