[Dovecot] dovecot 2.0 (latest on website), client workarounds?

What are the current valid imap_client_workarounds and pop3_client_workarounds? I had a tb-folder one, and outlook-idle i imap, and i kept getting errors. The only one that would seem to not give an error was

imap.conf: imap_client_workarounds = delay-newmail pop3.conf: pop3_client_workarounds = outlook-no-nuls oe-ns-eoh
