25#                include automatically expunged mails
26#  %{autoexpunged} - Number of mails that were automatically expunged after
27#                    client disconnected
28#  %{trashed} - Number of mails that client copied/moved to the
29#               special_use=\Trash mailbox.

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

86#     Same as disconnect-after, but tagged NO reply is sent instead of
87#     disconnecting the client. If the client attempts to FETCH the same failed
