Sendmail Not Excepting External connections

[Andre Cameron <acameron cybergnostic com>]

Hello,

Bit of an issue here.  I have setup sendmail a dozen times and have 
never had a problem.  Well I need this box here to accept mail so I edit 
the sendmail.mc and comment out the loop back line, I edit the 
local-host-names file etc make -C /etc/mail and restart sendmail yet the 
port is not open!  I can not telnet to it, nmap or anything else.  But 
if I do an NMAP on local host it is up and open.

So maybie the firewall is on right?  Nope, I set it to off and reboot 
but still have the same problem, any one here have any ideas?
