I am trying to sync a gmail inbox with dovecot 2.2.10 using the following config:

imapc_host = 64.233.171.108 imapc_user = %u imapc_master_user = master imapc_password = secret imapc_features = rfc822.size imapc_features = $imapc_features fetch-headers mail_prefetch_count = 20

# If the old IMAP server uses INBOX. namespace prefix, set: #imapc_list_prefix = INBOX

# for SSL: imapc_port = 993 imapc_ssl = imaps #imapc_ssl_ca_dir = /etc/ssl imapc_ssl_verify = no

And the doveadm command:

doveadm -D -o imapc_user=test@domain.tld -o imapc_password=password backup -R -x '\All' -x '\Flagged' -x '\Important' -u test@domain.tld imapc:

I am getting the error:

dsync(test@domain.tld: Error: Mailbox INBOX sync: mailbox_delete failed: INBOX can't be deleted.

What I really want to do is just sync Gmail's inbox, drafts, sent, trash/archive, and spam folders to my new system. Is this possible using imapc?
