Perl is probably a better solution, but I know sed better, so I wrote it using
that. The chr() function would be really be useful, though. I'll have to
look into changing my script to Perl, but for something quick and dirty, it
solves the problem today.
Now the trick of integrating it into procmail as a filter, and still allowing
