That uses 7 external processes when it can easily be done entirely in
procmail. At the very least, I don't see any point in doing md5 sums of
Here's what I use, it attempts to match only the actual address, without
* $ ^From:.*$\MATCH
The whitespace inside brackets is a tab and a space. The $\ syntax
requires a recent version of procmail.
