After trying for a couple of days I have come to the conclusion
that the Office 365 IMAP import tool uses the LOGIN authentication
mech while Cyrus requires PLAIN or stronger for proxying to work.

Even when only announcing AUTH=PLAIN in our server capabilities,
Microsoft executes LOGIN ... ...

(violation of RFC3501 section 6.1.1 ?
 dunno whether I am reading that correctly)

Is my conclusion correct ?
Any hacks or workarounds ?
