Despite this warning, this is EXACTLY what everybody uses STATUS
for. So recent IMAP extensions have directly addressed this issue.
You should upgrade to an IMAP server that supports LIST-STATUS
(and/or mailbox stat caching) if you want to see much improved
behavior. Or, the better solution, is to disable the option to
allow a user to poll all mailboxes. THIS IS A TERRIBLE IDEA AND IS
ALMOST CERTAINLY NOT WHAT THE USER WANTS. NO USER SHOULD BE
POLLING *ALL* THEIR MAILBOXES.
I mostly agree with the latter remark, but when using server side
filtering, I can imagine that people revert to this. It is a PITA
that one has to add each folder where messages are filtered into to
the list of folders that are checked for new mail.
Those who use server side filtering into separate mailboxes are smart
(read: advanced) enough to know that they need to poll those
mailboxes. If they discover, by chance, that they forgot to do this
once, it takes a second to correct this error.
And I totally disagree that just because you filter into mailboxes,
you want to poll. I have all sorts of filters setup to filter mail to
mailboxes, and I don't want to be bothered (pressured) into viewing
those messages (e.g. mailboxes used to archive list mail that I don't
actively read on a daily basis).
Allowing users to unilaterally (and one-click) poll all mailboxes is
simply a DoS waiting to happen. I continually am on the edge of
removing the feature. I have kept it in because it **may** be useful
for an installation with 1 (or a few) users. But it most certainly
should not be allowed if on a large installation, and should never be
the default option.
