  #   delay-newmail:
  #     Send EXISTS/RECENT new mail notifications only when replying to NOOP
  #     and CHECK commands. Some clients ignore them otherwise, for example OSX
  #     Mail (<v2.1). Outlook Express breaks more badly though, without this it
  #     may show user "Message no longer in server" errors. Note that OE6 still
  #     breaks even with this workaround if synchronization is set to
  #     "Headers Only".
  #   tb-extra-mailbox-sep:
  #     Thunderbird gets somehow confused with LAYOUT=fs (mbox and dbox) and
  #     adds extra '/' suffixes to mailbox names. This option causes Dovecot to
  #     ignore the extra '/' instead of treating it as invalid mailbox name.
  #   tb-lsub-flags:
  #     Show \Noselect flags for LSUB replies with LAYOUT=fs (e.g. mbox).
  #     This makes Thunderbird realize they aren't selectable and show them
  #     greyed out, instead of only later giving "not selectable" popup error.

  #   disconnect-immediately:
  #     The FETCH is aborted immediately and the IMAP client is disconnected.
  #   disconnect-after:
  #     The FETCH runs for all the requested mails returning as much data as
  #     possible. The client is finally disconnected without a tagged reply.
  #   no-after:
  #     Same as disconnect-after, but tagged NO reply is sent instead of
  #     disconnecting the client. If the client attempts to FETCH the same failed
  #     mail more than once, the client is disconnected. This is to avoid clients
  #     from going into infinite loops trying to FETCH a broken mail.
