German spam bounces

[Kevin Peuhkurinen <ke...@meridiancu.ca>]

Having gotten the spam under control, I found that I was getting bombed 
with tons of bounces as well.   So I made up a quick ruleset to stop 
undeliverables due to the german spam, using Raymond's ruleset as a 
starting point.  You can get it here:

It relies on the DSN containing the subject line, but that's fairly 
standard.

I was working on something for this problem today too, I have a fairly
simple way to determine a valid bounce vs. a forged bounce.  The attached
ruleset contains IP addresses for which my customers send their e-mail from.
If a bounce is valid, it would be expected to have my customers IP addresses
someplace in the message.  I check for this, if it's found, it's valid, if
not, it's faked.  Still more testing and more phrases to add, I've only had
20 minutes to work on this so far.
