QuickTip use exim for normal mail but stop for secure smtp server
Isn’t this weird? most people ask how to configure a mail server for secure smtp but one of my friend told me that he has a server which running Exim mail server on both port 25 (normal) and port 465 (secure smtp) now he is facing difficulties because the SSL certificates which Exim uses are expired. He wanted to close port 465 without affecting port 25 used by their scripts.
Here’s what I did and worked but if you have better idea or something to add, I’ll be glad to hear.
