comment Why don’t SMTP servers just require all senders to be authenticated before accepting mail?
If you run your own SMTP server, you can authenticate your users by maintaining an account for each one. However, this is not possible for other email servers (like gmail, hotmail,...). How can you do it?

comment Can Telnet to port 21 but not 25, 110
@DextrousDave: Can you telnet from inside your network? What is the exact error message you are getting? Do you have another router or firewall in front of this server?

comment Set DB proxy by using iptables
What are you trying to do? Why not just connecting directly to IP: 172.16.1.12. For port change, you can do it by configuring mysql server to listen on different port.

comment Get IP of the “requestor” when doing iptables NAT
I did not understand your rules well. If you want to redirect the traffic destined to 1.1.1.1 to be destined to 2.2.2.2, the first rule should be enough. In this case, you will see the original requester IP address. Using both rules, you are changing both the source and destination addresses!!

comment How to expose a UNIX domain socket directly over TCP
@SimonJGreen: Since this is not an interactive command that requires input, you can just try appending & at the end of the command.
