Yes, but it just struck me as impractical to poll for changes if
server-side notifications was possible/practical/"good practice" in
Camel.

I can do it with Brutus/Exchange using MAPI notifications and a waiter
thread on the Evolution side of things. No restructuring in e-d-s code
needed.

I would like to be able to distinguish between "auto sync"/"selecting a
folder" and manually pressing the Send/Receive button. Notifications are
not 100% reliable (best-effort only) so having a way to force a
refresh_info() is needed for my notification scheme.

Comments?
