Outlook/Outlook Express drove the change for us. They would open
multiple IMAP connections (sent folder, deleted folder, INBOX, ...)
but the only folder for which they would issue the IDLE command for
properly was the INBOX. From the behavior of other clients, many
had the same issue. Apparently Outlook counted on the IDLE for the
INBOX counting for all additional IMAP connections to the same
server.
