Gulp! It sounds like you've bitten off more than you can chew. How do you
know that is the case?

server is secure.

> How can I disable the port for sending mail out through my server.

Have you studied basic server and network admin?

> I would greatly appreciate your help.

Go back to basics, get on a course or two, hone your unix/linux skills
and understanding before letting yourself loose on the world of ICT.
