dovecot - Nov 2013 - Issue with postfix not handing over e-mails to dovecot

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.

Regards

Unless these are exceeding long, you probably should inline the contents
to save people from having to jump around to get the information to
help you.  It will also properly archive the context to the solution.
>From your logs, it appears your mail system does not know what user is
mapped to "someone at mydomain.com":

 	Nov  5 13:21:06 localhost postfix/local[11185]: 5716D8007B: to=<someone at
mydomain.com>, relay=local, delay=0.59, delays=0.57/0.01/0/0.01, dsn=5.1.1,
status=bounced (unknown user: "someone")

I don't know whether this message is produced by postfix or by dovecot,
but one thing I did notice is that your postfix configuration

 	mailbox_command = /usr/lib/dovecot/deliver -c
/etc/dovecot/conf.d/01-mail-stack-delivery.conf -m "${EXTENSION}"

has upper-case "EXTENSION", whereas the Dovecot wiki uses lower case:

 	http://wiki2.dovecot.org/LDA/Postfix

If that's not it, maybe it's your SQL.  You can also ask dovecot
to look up user "somebody" and debug your way from there:

 	doveadm user somebody
