I find that, in general, MH is a more capable mail handling system
than anything else I've used.

For example, with MH:

	pick -to current-users -or -cc current-users | xargs scan

would print a summary of all articles in your current folder which are
to: or cc: current-users (case ignored).

Or, more correctly, in this case:

	pick --sender owner-current-users | xargs scan

Or, if you wanted to select them all and keep them in a selection as a
whole, put them in a sequence:

	pick --send owner-current-users -seq current-users
	show current-users

will show all the articles from current-users, and leave the selected
in the "current-users" sequence, so afterwards you could refile them
all into their own folder with a single command (folder names start
with a "+" character):

	refile current-users +current-users
               ^^^^^^^^^^^^^ ^^^^^^^^^^^^^^
                     ^              ^--folder name
                     |-----------------sequence name

If you really want to know all that MH can do, retrieve the sources
and read the numerous docs.

Just for your amusement, I have appended a /bin/sh script which takes
all the messages in my inbox, which accumulate rapidly, and refile
them all into their appropriate subfolders, sorting them and packing
out all the empty holes in the numbering sequences automagically.
