But everything in one folder; not quite sure if IMAP (the protocol) is
going to be any good at that.
IMAP-the-protocol can be used, but most clients contain code like this:
open mailbox
for each message
do something
The 'do something' bit may be fast, but 'for each message' hurts.
IMAP doesn't force client authors to add that loop, but almost all of them
do add it, and it hurts when the mailbox is big. When I tested with a
"fast" client years ago, I got two seqscans and a 250MB download every time
I opened a million-message mailbox.
Someone told me that there are clients that avoid this. The default iphone
client, perhaps? Anyway, finding clients that don't try to download
something for each message will be the major challenge.
