You might find the tidy utility (http://tidy.sourceforge.net/) handy for this operation. It accepts the "-wrap N" option, which works great in my toolchains, but I've never tried it on Mailman archives.

fmt(1) is not robust, either. It will format the whole file with a single-minded determination. This includes mail headers, attachments, blah blah. it might even break the html. There are many unexpected consequences.

tidy won't break the HTML, at least, but there may indeed be unintended consequences. Testing suggested. :-)
