This is of no concern to me.  Such webmails are broken by
design, and need 
to be exterminated.  The fact that such webmails do not work
well now is a 
feature.

There are webmails which do NOT open a new connection for
each page 
refresh.  Natural selection should be allowed to take its
course.

The latter is of greater concern, but I fail to see this as
a major issue 
especially as it introduces a potentially major performance
burden with 
some mail stores.  There is a reason why STATUS does not
allow wildcards, 
and it is a terrible idea to move it into LIST.

We are seeing numerous IMAP servers out there, running on
major ISPs, 
which do not implement mandatory-to-implement facilities of
IMAP because 
it is too costly on the server.

You can NOT push excessive burdens on the server.  I
carefully designed 
IMAP to have a balance between server and client
requirements, yet the 
history of this community has been to make the server do
everything and 
boost the perception of IMAP service as being "too
expensive to run".

I find it sadly amusing that most of the recent discussions
are about 
esoteric features (ANNOTATE being an egregious example)
which will never 
be generally adopted in a world where we can't even count
upon SEARCH!

I fully agree with your sentiment.

To the original poster: One solution might be to use an
imapproxy and 
configure your webmail client to use that instead. I have
setup 
squirrelmail to do that. I don't know if squirrelmail is one
of the 
"should be exterminated" webmails or not, I like
it, but then many 
things people like are broken by design, sadly... Just as a
side note, a 
large Dutch isp called xs4all uses it for their customers.

Hope that helps.

Best regards,
Jeroen
