I am trying to build the most simple mail server ever.
So I installed exim (I'm running debian by the way) and changed only the nessecary things. And then... yay it works!
But there is one problem. I can send mails without giving a username and password? Well i think thats a bit to insecure. I did some research myself but I could only find very complicated things that require extra tools.
So is there a simple line I can put in my config file so that exim asks for a username and password if you want to send an e-mail?
Thanks in advance!
