Hi. Replication in dovecot is running into trouble as it is trying to sync virtual namespaces and does not like it. dsync parameters With v2.2.9+ you can configure what parameters replicator uses for the doveadm sync command: replication_dsync_parameters = -d -N -l 30 -U The -f and -s parameters are added automatically when needed. Usually the only change you may want to do is replace -N (= sync all namespaces) with -n <namespace> or maybe just add -x <exclude> parameter(s). ........ What is the description of namespace that follows -n or -x? -x virtual Or -x 0/ Where 0/ is the prefix for my virtual namespace Does not seem to stop it trying to sync the virtual namespace... What should I be doing instead? Do I need to use all the parameters above? Or can I just use the -x ? Sent from my iPa
