Courier is managed by a config package, but has a few quirks.

== Setup ==

 * Install the config package
 * Generate dh parameters using `/usr/bin/openssl dhparam -outform PEM 3248 >/etc/courier/dhparams.pem` (number of bits [[http://gnutls.org/manual/html_node/Selecting-cryptographic-key-sizes.html][recommended for "high" security in the gnutls manual). The courier `mkdhparams` script shipped with Debian Jessie (in May 2014) is broken and will always create a 768-bit key.
 * Edit `authdaemonrc` to set `authmodulelist="authpam authuserdb"` (the file is only readable by root and config package dev will not divert/transform it)

== Notes ==

 * Members authenticate using PAM and therefore read mail as their normal user
 * VMail users gain tokens via `/etc/courier/get-token` and a local modification to the courier `authuserdb` method
