So what part of the connection to you perceive as the most expensive?
The selection of the mailbox? This might be cacheable, but that depends
on how the webmail client is written (ie, simply caching it might screw
up some of the client's logic).
FWIW, Dave McMurtrie's imapproxy (http://www.imapproxy.org/) works quite
well with IMP/Cyrus, and is very well written. It doesn't cache the
selected mailbox, but it does keep an authenticated (and optionally
encrypted) connection open with the server.
