I see nothing in this that requires bash, so to make it more portable
you should probably just use /bin/sh

  | prefix=$(mhpath +inbox | sed 's,/inbox$,,')

This is just            prefix=$(mhpath +)

  | to=$(echo $2 | sed -e "s|^$prefix/||")

And in any reasonably modern shell (certainly including bash)
this is just
                to=${2#${prefix}/}
(and much the same for the assignment to "from" slightly lower).

  |     fromf=$(echo $from | sed -e 's,\(.*\)/\(.*\),\1,')

And this one could be
                fromf=${from%/*}
(and similar for others using the same pattern).

In general, it is rarely necessary (unless your regular expression is
truly complex) to ever do "echo thing | sed" these days, and much safer
in case "thing" has any meta characters (like folders with spaces in their
names...)

  |     fromm=$(echo $from | sed -e 's,\(.*\)/\(.*\),\2,')

This one is (I think)
                fromm=${from##*/}

  |         # Need to set the current folder back to $fromf!

You might want to consider folder -push and folder -pop to
better accomplish this.
