I don't know of anything standard, but it's very easy using procmail to
filter a message to a folder depending on the content of a header:  for
example, just write a little Perl script which takes as input an email
message, greps for List-ID: and returns a folder name based on the value
of the header, then uses formail to insert this into your own custom
X-My-Mbox-Header.  Then use a procmail recipe to put any successfully
matching messages into the results of $MATCH.
