I've still found filtering by From: header to come in useful in certain
situations. For example, when I'm on someone's mailing list and they don't
provide an opt-out method. Or when something like this happens:

+   495 Dec 27 Carol Jamison       (198K) BUILDING
+ N 496 Dec 27 Carol Jamison       (198K) BUILDING
+ N 497 Dec 27 Carol Jamison       (198K) BUILDING
+ N 498 Dec 27 Carol Jamison       (198K) BUILDING
+ N 499 Dec 27 Carol Jamison       (198K) BUILDING
+ N 500 Dec 27 Carol Jamison       (198K) BUILDING
+ N 501 Dec 27 Carol Jamison       (198K) BUILDING
+ N 502 Dec 27 Carol Jamison       (198K) BUILDING
+ N 503 Dec 27 Carol Jamison       (198K) BUILDING
+ N 504 Dec 27 Carol Jamison       (198K) BUILDING

(This person got some e-mail worm and keeps spamming me.)

That's why I was wondering if there's a nice script that I can drop in
~/.mailfilter that reads from a gdbm database to determine whether to
block this From address.
