Debian Wheezy Mail Server – Postfix Dovecot Sasl MySQL PostfixAdmin and RoundCube

Shamefully I didn't want to find my own way so the whole tutorial I followed is here.
For my personal further usage, I attached the working nginx, dovecot, postfix and php5 config to this post. There are two minor differences from the original tutorial: I don't use spam filtering because at me it's done by a 3rd party provider. Second, I use an outgoing TLS smarthost via mail submission 587 port, detailed in the postfix/main.cnf.
Note that sensitive infos are all removed and in the tgz there is a missing sock, obviously, because sockets can't be packed. (tar example/php5/fpm/socks/ssl_example.com.sock: socket ignored.)
Follow the original howto first.
