Sendmail refusing connection

[Payne]

Hi,

I have installed FreeBSD 5.2 and I am trying to get to access mail from  
the outside world. But when I do a telnet to port 25 I get this error,

telnet mail.eatme.com
trying xxx.xxx.xxx.xxx

telnet: connect to address xxx.xxx.xxx.xxx: Connection refused

where do I need to go to tell my server it ok to access mail.

Payne


Please note that eatme.com and xxx.xxx.xxx.xxx are flake to protect the 
real server.
