Before I head off to read RFCs, and try to understand what Cyrus is doing and Thunderbird, and what is going wrong, I just wanted to ask if anyone already knows the answers. Specifically, using LIST-EXTENDED, should a mail client be able to determine which folders are subscribed to, and if so why is Cyrus apparently not returning that information? Conceivably TB is doing it wrong though. And if TB is trying to set a \Subscribed flag on a folder, should that be updating Cyrus's list of subscriptions?
Anyhow, I'll see if I can get some traces of what's going on, and see if that's what should be going on. Thanks, g
