postfwd for Debian
------------------

1. PROVIDE A CONFIGFILE
-----------------------

Please provide a config file, usually /etc/postfix/postfwd.cf. Examples are
located in /usr/share/doc/postfwd/examples/.
Another can be found at http://hege.li/howto/spam/etc/postfwd/postfwd.conf
and is provided as example-cfg2.txt.

A quickstart guide is available at http://www.postfwd.org/quick.html and the
online documentation at http://www.postfwd.org/doc.html, the offline version
can be viewed with 'postfwd -m'.

2. VERIFY CONFIG
----------------

How interpret the parser your rules, you can check with:

# postfwd -f /etc/postfix/postfwd.cf -C -v

Check your rules against sample request:

# cat request.sample | postfwd -f /etc/postfix/postfwd.cf -L

# cat request.sample

Samples can be taken into the logfile when starting the daemon with "-vv"

3. AUTOMATIC STARTUP
--------------------

In order to avoid the startup of the daemon on an unconfigured machine,
automatic startup, on boot, is disabled by default. To enable it just run
'systemctl enable postfwd.service', when still using SysVinit edit the
file /etc/default/postfwd and set the "startup" variable to 1.

4. CHOOSING WHICH POSTFWD VERSION TO USE
----------------------------------------

Since some time, there is also a prefork version available, called postfwd2.
You can use update-alternatives to choose between 'postfwd1' and 'postfwd2'.
