Evolution sucks for IMAP. Sadly the competition sucks even more. I deal with several thousand mails per day using Evolution and vfolders and I far too often find myself waiting as Evolution goes off in a trance for no good reason - there is a reason, it has decided to do something silly with IMAP server, it's just not a _good_ reason.

Today I did my semi-annual checkout-if-any-of-the-competitors-have-stopped-sucking-yet. The answer was a resounding "no". I watched sadly as Thunderbird, Balsa and Sylpheed all started downloading message headers 1 at a time from the server, destined to finish some time next year. Kmail was reasonably snappy and seems to actually take advantage of some of IMAP's goodness however searching by "any recipient contains" just got me a while bunch of error messages. It seems it has no idea which kinds of searches are available on an IMAP server.

It really makes me wonder does anyone actually use IMAP or do they just develop the code with test accounts on test servers :(

I use Thunderbird with IMAP and it's OK for my needs.  While I agree that most IMAP clients
suck, you have to realize that IMAP as a protocol sucks.  It's really a horrible protocol; the
best IMAP client I know of is "Pine" (or "Alpine") and one of the authors of Pine was the main
IMAP RFC author, so I'd hope he'd get it right!

For Thunderbird 3, I'm not that interested in an integrated calendar.  I would prefer some
kind of tagging mechanism to tag messages (with arbitrary numbers of tags per message) and
then filtering on tags to make virtual folders.

Yes, I've written a few scripts to do bulk operations in IMAP and it definitely seems like a protocol that just grew and the was documented but that is no excuse for clients doing:

Fetch message 1 header.
Thank you.
Fetch message 2 header.
Thank you.

when they should be doing:

Give me all the message headers.
Thank you.

The same goes for moving/copying messages. IMAP support always seems to be bolted on afterwards

Sadly, that's true. I can imagine the development going something like this:

"Aaaah! There are all these weird mail stores out there. Let's abstract out a generic mailstore and specialize it for each actual store."

"OK, what can a mail store do? Well, let's look at POP3 and see.."

The generic mail store API is then designed around POP3 and has no idea how to use the more advanced facilities offered by IMAP. :-(
