Postfix doesn't connect to telnet

Are you wokring from outside of your network? Check if your 25 port is not filtered somehow ... if you running Linux on your client machine .. do this: nmap "yourserveripgoeshere" ...it will show you if your 25 port blocked or not.

 

As you can in my previous posts the port seems to be opened

I can try to telnet on localhost or from outside, the result is the same

telnet localhost 25

telnet serverip 25

 

I just don't know how you sure in this information ... if I see (without your IP) ... the result of nmap command ... than we can continue our conversation .. otherwise .. I can't locate an issue.

 

This is the ip 94.141.20.33 (the mail server will be mail.giannileggio.com)

Thank you for your help

 

ok ... everything is ok with ports ..here is result of nmap
