I very much like the focus of bogofilter -- do one thing fast and well. But I
also want to make sure I'm doing what I can outside of it to keep it working
optimally. Spamassassin has the bayes_ignore_header feature, but I've missed
anything similar for bogofilter (not a criticism!), so I've written a small
filter to strip out locally-added headers before training. I don't want to
use -H because there are plenty of useful tags in the headers that I DO want
scored.

Perhaps I'm going about this the wrong way. Is there a way to flag a
phrase/header so it's NOT used in scoring one way or the other? To "drop" items
learned in error? I could then just feed a file with "things to ignore" once.
I've re-read the manpage, but don't see anything obvious.
