Well, I actually have an awk script that mangles the headers and posts each
message to a local news group (not forwarded anywhere).  So, the unsubscribe
filter is only a little tweak to that.  My script already buffers the entire
body just to get the number to put in the Lines: field.

But it shouldn't be hard to build your own little awk or perl script and put
it in your .procmailrc, like:

:0 w
* ^From owner-freebsd-hackers
| guff_filter | rcvstore +hackers

This assumes you are using MH (the world's greatest mail reader).

The snip of awk that does the deed is:

function trim_hack(n, lines, group)
    {
    if (lines[n-2] !~ /^$/)
        return n
    if (lines[n-1] !~ /^To Unsubscribe: send mail to majordomo@FreeBSD\.org$/)
        return n
    if (lines[n] !~ "^with \"unsubscribe (freebsd-)?" group "\" in the body of the message$")
        return n
    return n - 3
    }

Make of this what you will. :-)

I never actually catch up!  I scan the recent topics and dive in when I can.
Expire takes care of the rest.  I wouldn't have time to read any code if I
read all the lists.  All the politics and scuffles are entertaining for a
while, but I'm really in it for the low level bit shuffling. ;-)
