Re: Using dsync for a single mailbox?

Something like this on the new server: doveadm -o imapc_server=remote_ip -o imapc_port=remote_port -o imapc_user= -o imapc_password= backup -u -R imapc: The best I can do is get it to complete without any errors but without transferrig any mail. I've added the imapc config to local.conf, and I run it like this: doveadm -Dv sync -1 -R -u local_user -m mailbox_name imapc: (or variations on that, e.g. with -n namespace). It successfully logs in to the remote imapd, but doesn't decide to transfer anything. If I leave off the "-m mailbox_name" it does start traversing the remote maibox hierarchy, but I really don't want it to transfer everything --- just some specific mailboxes. One thing that's unclear to me is exactly what strings I should pass to the -n and -m flags. Do I specify a namespace by its local prefix, or its remote prefix, or its name in the config file, or ... ? And mailbox names? How does dsync map remote to local names?

Re: Dovecot and archived compressed folder
Hello, yes I know about this plugin. But I don't know how to implement to have normal e-mails without compression and mail archive compressed by this zlib plugin.
