Harry, if it was simple to weed out spam, everybody would do it ;)

Can you post a typical message header *after* it has been weeded by
outlook and I'm sure someone will have a go at it.

For now, this recipe kills all mail sent by people/addresses in the the
file ~/Mail/blacklist. It works by first extracting the values of four
header-fields and the matching them to the lines in ~/Mail/blacklist
one by one.

:0 :
* ? formail -cx"From" -cx"From:" -cx"Sender:" -cx"X-Envelope-Sender:" | fgrep -is -f ~/Mail/blacklist
~/Mail/spam

Should I send you a copy of my el-mucho commented spam-weeding
procmail-file? It catches almost all of my spam, with very few false
positives, and has features such as blacklists and whitelists builtin.
All that is needed is to change a few variables (e.g. my name for
yours).
