Subject: [PATCH 49/82] imap: EXAMINE/STATUS: return correct counts
Date: Wed, 10 Jun 2020 07:04:46 +0000 [thread overview]
Message-ID: <20200610070519.18252-50-e@yhbt.net> (raw)
In-Reply-To: <20200610070519.18252-1-e@yhbt.net>
We can share code between them and account for each 50K
mailbox slice. However, we must overreport these for
non-zero slices and just return lots of empty data for
high-numbered slices because some MUAs still insist
on non-UID fetches.
