If you cant telnet on port 25 then a remote client will not be able to 
connect via smtp to send mail.

Check if postfix is listening on port 25 of the ip that you are trying to 
connect to using :-

(as root)

netstat -apne | grep postfix

there should be a line including x.x.x.x:25 (or 0.0.0.0:25) and LISTEN  
(x.x.x.x = your server ip)

if not, ie you only have a 127.0.0.1:25 line, then your postfix 
configuration isnt correct, or isnt being loaded, which can happen if you 
are running it in a chroot environment.
