It is possible, although you should use mode 1 or 2. Mode 3 is DB only and
4 only reads on startup (nothing written).

I suspect here is your issue - although it's difficult to know based on the
information provided why there are no domains in the list.

Was this command issued on the sender or receiver? If the receiver, do you
have a call to save() in your config? I believe this is parsed at startup
to determine which domains to create in memory - so realistically, the
configs on all nodes should be identical (or at least contain the same
REGISTER handling logic).

Otherwise, did you have this working without DMQ replication (i.e.
replicating via DB only)?

Cheers,

Charles
