I tested a local build with that patch and I don't think it is a complete fix. In our setup, it stalls replication for our webmail users who use the Roundcube sieve plugin:
Sep 05 23:21:04 <obfuscated> dovecot[12574]: doveadm: Error: Exporting mailbox INBOX failed: Mailbox attribute vendor/vendor.dovecot/pvt/server/sieve/files/roundcube lookup failed: Mailbox attributes not enabled It's possible that our Roundcube configuration is doing something odd with sieve, but sieve filter replication with this setup worked before this bug was introduced. Thanks, James
