On one of the lists that I subscribe to, there are at least 4 or 5 people
each day that send unsubscribe messages to the list. Worse, none of them
can spell it right. "unsiscribe", "unsuvscribe", etc. I've been able to
filter them out if they put it in the header, but I don't know what to do
to get Procmail to search the message body. How can I do this?
Here's a part of my multi-line defense agains unsubscribes. (I wish
the maintainers of +this+ list would set up something like this at the
list server end.)

These have evolved over time so now that I look at them again all in
one place, it's obvious that they could be, er, fixed a little bit.
Nevertheless, hope this can help somebody.
You might want to exclude the check for message size. It has never
appeared to be too high but on the other hand, a lot of the normal
messages I receive are below 2000 bytes, too.
If you need to know how to set up a mail filter or defend against
emailbombs, send me a message with the words "get helpfile" (without the
" marks) in the SUBJECT: header, *NOT THE BODY OF THE MESSAGE!* I have
(Scanning of body -- B option -- could be helpful here as well :-)
