[Mimedefang] Recycling procmail recipes

[Kenneth Porter]

I was looking at a page with a procmail filter for dealing with TMDA 
bounces:

<http://www.softwolves.pp.se/blog/2004-06-23,en>

It struck me that it might be useful to use the filter with minor editing 
directly in MD in some way. Is there a Perl module that can parse procmail 
recipes, or has anyone come up with a clever way to convert a procmail 
filter to an MD filter subroutine?

For this case I probably just want to reject the message.
