Implemented it now to v2.0:
http://hg.dovecot.org/dovecot-2.0/rev/5f64f935e64b

You could test this by first verifying with older Dovecot or another
IMAP server that Outlook/OE/etc. actually uses some IMAP extension, such
as IDLE. Use e.g. Dovecot's rawlog or some traffic sniffer. After this
try Dovecot v2.0 and see if it's still using the extension.
