After yet more testing, I did a recursive copy of the old 49 GB Maildir

You probably copied a large number of sparse files where the holes
got expanded. If you use rsync with the -S flag (or use tar) you
should end up with a similar disk usage on the new machine.
I did actually consider this. I had tried (after deleting the copy):
rsync -avzS
No change - still 188 GB. So I've just tried (again after deleting the
copy):
rsync -avS
... in case using compression somehow negated the sparse files setting.
Again no change - still 188 GB.
Mysterious.
