One of them reported, that he does not always see new mail. That user is using Mozilla Thunderbird (1.0.7). Looking a bit with him at the workings, I can see the issue. He has the IDLE extension enabled.
I've fixed a couple of problems with IDLE since alpha5. Maybe those will help?
However when sniffing the network, I see that sometimes when switching to another mailbox, the SELECT command is not always sent to the server. At the beginning, INBOX is (always) selected. Then another mailbox is selected, and usually a SELECT command is sent and the mailbox is seen. But going back to INBOX again, often no "SELECT INBOX" is seen on the wire. Then of course he sees no "EXISTS" or anything like that.
Thunderbird by default uses multiple IMAP connections. Did you check the others?
