Hello, Does Cyrus IMAP support RFC 6154 about special-use mailboxes? https://tools.ietf.org/html/rfc6154 I read that it only wass supported in Cyrus version 2.4 ? I am using version 2.5.10 (from Debian 9). Can I put this in imapd.conf for all users? xlist-archive: Archives xlist-drafts: Drafts xlist-sent: Sent xlist-spam: Spam xlist-trash: Trash Is it only used on new created folders or always? Do I need "specialusealways: 1" or something like that? What about client-support? Is it much used in clients?
