[Dovecot] Issue with postfix not handing over e-mails to dovecot

[Tru Pheenix]

Hello!

I have installed postfix with dovecot and postgresql. I have set up SASL
authentication for postfix and dovecot and been able to test them
successfully. I am able to send sasl authenticated emails through smtpd on
postfix using a mail client like Thunderbird. However, now I am unable to
receive any e-mails. When I respond to the emails, I get a not delivered
failure from postfix. I cannot figure out why postfix is not handing over
the e-mails to dovecot.

So here are some links to follow:

posftconf output: https://gist.github.com/anonymous/7318863
doveconf output: https://gist.github.com/anonymous/7318896
tail -f /var/log/mail.* output (when receiving mail):
https://gist.github.com/anonymous/7318945

Any help to solve this would be highly appreciated.
