i am new in postfix . please advise me.

Thanks

if you can't even connect to port 25, clearly postfix isn't running, isn't configured to listen on that ip address or you're firewalled. as for port 110, that's pop3, which is nothing to do with postfix in the slightest.

Now the both are working

telnet it.tuxnet.com 25

I am not able receive any mails local domain and other domain.
Please advise me.

Thanks
