I'm in the process of getting my head around the least painful path to 
convert everything to maildir, given the headaches mbox is giving me here.

It looks like I can leave mail_location unset, and use a basic namespace to 
force the separator to be the same as for mbox:

namespace private {
   separator = /
   inbox = yes
}

procmail is used as the LDA on CentOS so I then need to change procmailrc 
to direct incoming mail to Maildir, presumably by adding:

MAILDIR=$HOME/Maildir
DEFAULT=$MAILDIR/

It looks like I can do this on a per-user basis by putting that in a user's 
.procmailrc until I migrate everybody.
