(unknown charset) expiring old message

Howdy All!

Is there a way to do something like, say, delete or archive all messages more than 12 months old, or a better way to re-index .html files than: whack all the old stuff
convert *.html to mbox file
rm *.html
convert mbox to .html

Im starting to see this whole re-indexing thing as a major drag with hypermail.

EAK.
