Thanks for all your comments.  I pay for a Business type DSL with 5 ip
addresses and I am allowed to run all my own servers.  I didn't have this
issue until I re-complied my kernel with the IPFIREWALL option.  I have
now resloved the issue.

Basically what I did was move the rule for port 25 to the top of the list.
 Changed the add 04010 to 03001.  When I did a nmap on the localhost I
could see port 25 open, but when I did the nmap from one of my other
servers on the same subnet, it did not list port 25.  A quick reboot of
the server, and all is well.

Thank you all for your comments.
