Postfix authentication problem

June 2, 2014 2.4k views
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 (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. I hope you can help me and guide me Thank you.

Are your using another SMTP server like Google, Hotmail, or something similar as a relay? If you are doing that with a custom domain, make sure you have your MX records set up correctly. If not, it will look like you are claiming to send mail from a domain that it doesn't really originate from. That's a quick way to get flagged as spam.

Andrew, thanks for replying, I have logged the mx, as indicated in this post:

Perhaps it may be because I'm missing header:

-Outgoing X-Spam-Status: No, score = -2.9
X-AntiAbuse: This header was added to track abuse, Please include it With Any abuse report

How could install the program scan or post me manage them?
