I understand that I posted this before, however I left out some very important details which apparently made a lot of people less likely to answer, here's a more detailed version.
My postfix/dovecot/mysql virtual mail system is not receiving mail and is not sending it. When sent it goes to the mail queue. I'm stumped and have no idea what to provide you with, so if you ask I will put it up.
I used this guide: https://www.linode.com/docs/email/postfix/email-with-postfix-dovecot-and-mysql
My postfix main.cf:
# See /usr/share/postfix/main.cf.dist for a commented, more complete version

# line of that file to be used as the name. The Debian default
# is /etc/mailname.

And which file do you need for dovecot?
