Yep. Get it on the same network as the server and run the command:

telnet 192.168.10.1 25
Now guess what - it says

telnet: Unable to connect to remote host: No route to host

That's not good.

Show us these:

1) ip a l         (ip address list)

2) ip r l         (ip route list)
 From my laptop or from my server?

 From your mail server.
Good morning - in the meantime I fell asleep ...
but here are my server's results:
