Thread: what do I need smtp server for?

-

i have vps ubuntu server , have set postfix because want use domain email though it's forwarding:
info@mydomain.com --> my.main.email@gmail.com
don't use server sending emails or thunderbird or so.

question need smtp server? can block access smtp port (25)?
because i'm not sure have secured smtp server enough.

if you're going use postfix installation forwarding emails, , you're not expecting mail outside network, can safely leave port 25 closed.
