[baylisa] Matching envelope "From" header using SpamAssassin

Tue Feb 4 20:02:16 PST 2003

I never use "To" or "Cc" for filtering list mail.  Most mailing list
managers insert some kind of header that can be used, such as
"List-Id:" or "Sender:" or "X-List:" or even "X-Unsubscribe:."
These are preferable for filtering, as it helps you distinguish list
mail even if it is BCC'd.

There's no need for the SpamAssassin rule though; just put the rule
for '^From .*owner-foo-bar' in your .procmailrc ahead of the
SpamAssassin stuff.
