Exclude namespace from replication

Hello list,

I am using replication with dsync and I am facing some issues with shared folders. More particularly expunged message reappearing. I have searched a bit and it was suggested that shared folders should not be synced.

My namespace looks like that:

namespace { inbox = no list = children location = maildir:/usr/local/vhosts/mail/%%d/%%n:LAYOUT=fs:INDEX=/usr/local/vhosts/indexes/%d/%n/shared/%%u:INDEXPVT=/usr/local/vhosts/indexes/%d/%n/shared/%%u prefix = shared/%%d/%%n/ separator = / subscriptions = no type = shared }

I was wondering if defining:

replication_dsync_parameters = -d -N -l 30 -U -x shared

Is enough. Or do I need to change the syntax of the namespace like that:

namespace shared { .... .... type = shared }

Thanks for your help
