In a formerly working environment suddenly clients aren't notified of new emails and can't retrieve new emails. Server is Ubuntu 11.04 dovecot 1.2.15. Clients which fail are a Pre2 webOS 2.1 and TouchPad webOS 3.0 (those are OS versions, I don't know which particular flavor/version the IMAP clients are); there is also a Thunderbird 3.1.11 client on the same system as the server which works properly. The clients never report an error. I got as far as configuring rawlog:
in: ~A2 NAMESPACE ~A3 SELECT "INBOX" ~A4 LIST "" * ~A5 UID STORE 0 +FLAGS.SILENT (\Seen) ~A6 UID STORE 0 +FLAGS.SILENT (\Seen)
out:

I've searched and read messages saying that there is no such thing as UID 0. Okay. Why are the clients suddenly trying to use it? Why doesn't the server just ignore it? (it seems like it may be terminating the connection)
What can I do about it? (I'll nag HP about the client side but I don't expect quick action. The server on the other hand is in my house.)
