1) Replicator syncs all users at startup. If you can change your userdb iteration to return only one test user for replicator that avoids it. (You may be able to do protocol replicator { userdb {..} } and protocol !replicator { .. })

2) You can enable replication plugin only for one user by changing mail_plugins setting via userdb extra fields.

Anyway, replicator simply runs doveadm, so there's not much that can go wrong. So you could even ignore 1) and just let it sync everyone at startup.
