`sortby`

Here's another MH utility
It sorts the messages in a folder into order by something other than date
(MH has a sortm command, but it won't do this)
- (You can say MH sortm -textfield From)
- (But the primary sort is still by date)
- (This is typical of MH's boneheadedness.)
sortby -field From -reverse -verbose
- Or sortby -f From -r -v
-field defaults to Subject
