Pardon my ignorance as I am not familiar with mailman and its storage
format but I assume that running the mailbox through a Sed filter to change
Minnie to newmin would not work???  Minnie and newmin are the same length.
Any size data would therefore presumably remain valid. This assumes the
mail archive is text based for the most part.

Just thinking out loud....
