But 'afew' supports it:

a) It supports tagging mail based on list-id.
b) It supports moving messages across folders (afair, but I have never used
that feature).

So combining both should give you effect you want.  I really recommend
you to take a look at 'afew'.  It helps a lot with initial tagging.
