Subject: [PATCH 45/82] imap: omit $UID_END from mailbox name, use index
Date: Wed, 10 Jun 2020 07:04:42 +0000	[thread overview]
Message-ID: <20200610070519.18252-46-e@yhbt.net> (raw)
In-Reply-To: <20200610070519.18252-1-e@yhbt.net>

Having two large numbers separated by a dash can make visual
comparisons difficult when numbers are in the 3,000,000 range
for LKML.  So avoid the $UID_END value, since it can be
calculated from $UID_MIN.  And we can avoid large values of
$UID_MIN, too, by instead storing the block index and just
multiplying it by 50000 (and adding 1) on the server side.

Of course, LKML still goes up to 72, at the moment.
