Subject: IMAP: Adjust dovecot configuration to bullseye.

Provisioning /etc/dovecot/conf.d/*.conf is a pain on upgrade so we
consolidate that by reverting these files to the distro-provided ones
and shipping a single /etc/dovecot/conf.d/99-local.conf override
instead.

-# If nothing happens for this long while client is IDLEing, move the connection
-# to imap-hibernate process and close the old imap process. This saves memory,
-# because connections use very little memory in imap-hibernate process. The
-# downside is that recreating the imap process back uses some resources.
-imap_hibernate_timeout = 15s
-
-# Maximum IMAP command line length. Some clients generate very long command
-# lines with huge mailboxes, so you may need to raise this if you get
-# "Too long argument" or "IMAP command line too large" errors often.

-#  %{fetch_body_count} - Number of mails with mail body data sent to client
-#  %{fetch_body_bytes} - Number of bytes with mail body data sent to client
-#  %{deleted} - Number of mails where client added \Deleted flag
-#  %{expunged} - Number of mails that client expunged, which does not
-#                include automatically expunged mails
-#  %{autoexpunged} - Number of mails that were automatically expunged after
-#                    client disconnected

-# Workarounds for various client bugs:
-#   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.

-#     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.
