Perhaps a similar problem (but not as annoying as unexpunge) is other
manipulation like with ipurge: if you ipurge Trash folders or so, this
is not propagated to the replica - unless the user actually does
something else with this folder (open it or so, and a complete resync is
done - manual sync of a user does the same). So if the roles are
switched, old mail will show up in the folders again... :-)
(Still better though than not having undeleted messages.)
