Basically I have a Ubuntu Server machine and I would like an idiot-proof solution for sending emails from my website that is also running in this same machine.
My doubts are:
1) Should I use postfix or there are more simple solutions for an smtp server?
2) Do I need to be able to receive emails as well? I just want to send emails...
3) I did I simple test with postfix that came with my Ubuntu server and the email got sent, but it went to the spam box of my gmail. Anyway to avoid the spam box?
4) The email sender was email@example.com. How do I change that?
Thanks very much!
