Maildrop cant help with this, and there are no quotas possible
if you to add or delete anything in the maildirs.

Package: drsync
Status: install ok installed
Priority: optional
Section: misc
Installed-Size: 76
Maintainer: Paul Hedderly <prh@xxxxxxxxxx>
Version: 0.4-1
Depends: rsync, perl, libgetopt-mixed-perl
Description: Two-way remote file synchronisation
 drsync.pl uses rsync to synchronise between two directories
 (local or remote), but stores state information for files,
 so that it can be used in both directions, and can
 cope with files created, modified or deleted in either
 repository.

Unison does about the same, but is very picky about the versions
installed on each end.


Just dont expect this setup to uncrease the availability in
case of a crash - if the files on either end get corrupted
or vanishing this will be also propagated to the other side.
