Subject: [PATCH 52/82] imap: SEARCH: clamp results to the 50K UID range
Date: Wed, 10 Jun 2020 07:04:49 +0000	[thread overview]
Message-ID: <20200610070519.18252-53-e@yhbt.net> (raw)
In-Reply-To: <20200610070519.18252-1-e@yhbt.net>

We won't support searching across mailboxes, just yet;
but maybe in the future.
