Locahost.com resolves to the 10. Address as listed below:

-bash-2.05b$ host localhost.com
localhost.com has address
localhost.com mail is handled (pri=10) by ghost.localhost.com

You need to have the following line in your config:               localhost localhost.my.domain

Where you change localhost.my.domain to whatever your machine resolves to,
or just leave it the way it is.  Don't, however, use localhost.com.  That is
a valid DNS name and belongs to someone else.

If your aren't running DNS locally, make sure you have the following in your

domain  <domain name>
nameserver  <ip of your ISP's DNS>
