Postfix authentication problem
hello. I installed postfix, and I can send and receive emails from any external server, however my emails land in the spam folder. I know, it's for authentication, as well as my domain to my ip, I really do not know which file I should set and where. I want to see the source code of my email, so they can help to detect possible error, I leave here. The code may be aware that the sender goes 127.0.0.1 (not Salé and my ip or my domain, I hope you can help me), actually I'm newbie, but I have learned a lot reading. http://pastebin.com/SAFcz9AM I hope you can help me and guide me Thank you.
