Thunderbird normally keeps at least one, and often _several_ IMAP connections open per user. You may find it helpful to tune different front-ends according to the type of client connecting. Desktop clients tend to hold connections open for long periods (all day), whereas webmail implementations typically open and close a large number of connections, and some mobile push providers who don't support IDLE (eg RIM Blackberry) will poll for each user every few minutes. As Wes points out, proxyd process churn is relatively expensive. LZC> IDLE imap command is compatible in Cyrus Murder enviromment ?? Yes. In your non-referring scenario, the proxyd process on the front-end will hold open its connection to the backend and report IDLE updates just like a single-box Cyrus system.
