this has one drawback:  your procmail/perl prefilter has to know the
folder names you are going to use, as does the MUA.  theres a spot
that can get out of sync:  each time you make or change folder names,
two places have to get updated.  it was better to use intermediate
names to get an abstraction layer, or, much simpler, use the mailing
list posting address in the standardized header, then have the MUA
just filter on this one header.
