Basic question for email server

view story

http://forums.fedoraforum.org – Hey all, I have a very basic question. Do I need anything besides Postfix to receive emails? To send them out, I use SendGrid, but I can't seem to grasp the basics for receiving emails. I would guess that when someone sends it to [email protected], the traffic would find it's way to domain.com and the server would put it in example's email directories. Is it really that basic, or am I missing something? If you know of any prior posts that reference these basics, please send them my way. And thanks again for the help! ---------- Post added at 11:06 PM ---------- Previous post was (HowTos)
