Maybe, but that is not feasible in our deployment, which is LDAP driven
and thus looks like this:
mail_location = maildir:%h

Changing this in-situ by attaching a "/Mail/" to the location for literally
hundreds of thousands mailboxes clearly is a no-go, nor would I look
forward to go fix up all the other places and scripts that assume a
certain directory structure.

Regards,

Christian
