Well, you guys make an IMAP server that follows the latest IMAP protocol
enhancements. Even the proposals that are still in draft like QRESYNC.

And some of the people who work on these standards are employed by
Isode. It's just fair to mention that.

With your help I managed to get my hands on one that does things like
QRESYNC, CONDSTORE and ENABLE (which I also had to add, didn't knew
about having to ENABLE them too). So I can now start trying to get it
actually working too.

Good

Awesome! And let's convince the latecomers to hurry up with it. It does
make quite a lot of things more easy. Especially the VANISHED response
is very useful indeed.

No more fiddling with sequence numbers and single line EXPUNGE
responses, and all immediately in the SELECT's response packed together
with the flag updates.

I wish certain IMAP developers, who's name(s) shall not be pronounced,
would read the specs too :-\. That would make the lives of client
developers far less frustrating.

Aha okay (so .. I can just remove the items with that UID) :)

Will do. Although the porting of all this to Evolution will not be for
tomorrow I think. 

Well, CONDSTORE and QRESYNC are more easy for them to backport to
upstream Camel. IDLE is a bit more difficult as this involves dealing
with the events in their ui pieces too (and the patch for IDLE is a
little bit ugly as I had to do certain things that are not possible with
how the stream-related code is structured in upstream Camel).
