All you have to do is tell your MUA to "subscribe" to the folders you
want
checked. (Or rather, tell you rserver you are subscribed to the
folder. Any
IMAP client that connects to that account after that will check all
your
subscribed folders.)
What IMAP clients have you used?
None of the clients I have experience with do that. (Actually they all
do at startup, but not on the periodic mail check. I do know of one
that does it periodically for my platform, but I am not interested in
using that client at this time for other reasons.)
I'm not even sure there is a good way to do it in IMAP for an arbitrary
number of folders. Maintaining N connections to the IMAP sever to
monitor N folders can be expensive if N is large. The IMAP STATUS
command will give you the answer that you need to update the unread
count for the mailbox, but the IMAP spec specifically says that STATUS
is not guaranteed to be a lightweight operation, so it is probably
unwise to run STATUS on N mailboxes every M minutes if N is large and
you have more than a few users on your server.
I still don't have a solution that doesn't feel clunky. (I'd prefer not
to have to filter on the client, except for spam filtering, because
this means synchronizing filters between at least 2 clients.)
