to work with current murder/replication? Or is this something else?
In the "replicated" mupdate_config, each backend (nothing to do with
replication) is meant to serve data from a common mail spool, while
maintaining a "replicated" copy of mailboxes.db. The changes to
implement this IMAP_ENUM_MUPDATE_CONFIG_REPLICATED are isolated to
imap/mupdate-client.c, effectively to just remove references to the
backend server. So, this configuration would remove the various
locking problems surrounding mailboxes.db, since each backend would
be maintaining a separate copy. Any concerns related to locking in
the mail spool would still be relevant, tho that locking is typically
less esoteric. You'd need to have an mupdate master as well.
