I have set up a mail server on ubuntu.

Ive checked ports are open and I've double checked all config files, checking with every google search result I could find. Most of the similar posts have more complex logs and outline steps I have already taken.

I can send emails from my server no problem, but I can not receive them.

Here is the mail log after trying to an email from my university email, and my gmail email:

    What is your Postfix configuration? What steps have you already taken? – Michael Hampton Jan 03 '15 at 20:25
  • Ive actually dont quite alot, too much to list, I was hoping my log would help. Ive added the main.cf file to my post. The master.cf was only touched in 3 places from default. I removed the comment, thus enabling, smpt, smpts, submission, -inet. Thanks. – בנימין הויי Jan 03 '15 at 20:51
  • In the future, you should post the output `postconf -n` and/or `postconf -Mf` to show contents of file `main.cf` and/or `master.cf` respectively :) – masegaloeh Jan 03 '15 at 21:48
  • @בנימין הויי: re your flag: Nothing dramatic, don't worry. People would have told you. – Sven Jan 05 '15 at 17:15

Your mydestination does not include your own domain, thus Postfix doesn't know it is meant to deliver the mail locally. This is why you see errors like "Relay access denied" and "Mail loops back to myself".

It appears you had already set this up, but had commented it out.

#mydestination = vapsterthekoala.com, makaveli, localhost.localdomain, localhost
mydestination = localhost

Simply add your domain name to mydestination and reload Postfix.

I dont know what I did wrong, but redoing the setup all over again fixed the problem. A guide for those who are interested. https://www.linode.com/docs/email/postfix/email-with-postfix-dovecot-and-mysql#postfix
