You don't.

Your RDNS record is managed by your ISP (99% of the time.)  Contact your ISP and request they define a RDNS record for the IP address your mailserver is using to SEND mail.  Some may argue the RDNS name should match the name your mail server identifies itself with when communication with other mail servers.

It wouldn't do any harm to set up an SPF record while you're at it...  http://www.openspf.org/
