smtpprox-loopprevent for Debian
-------------------------------

smtpprox-loopprevent needs two port numbers, one it listens on and the other
it sends to (eg. forwards mail back to postfix here).  Set them in
/etc/default/smtpprox-loopprevent.


Postfix
-------

You must configure postfix to use smtpprox-loopprevent.

There is no one-size-fits-all postfix configuration, you'll have to investigate
and integrate.  I have copy/pasted the master.cf config example right from
http://www.postfix.org/SMTPD_PROXY_README.html#config and it has worked.

If you have another before-queue content filter (such as dkimproxy), you'll
need to have one forward to the next.  (You might use smtpprox-loopprevent
first, it's more light-weight.)
