Based on this thread, it sounds to me like Outlook expects the *same*
ticket (or more generally resumable session) to work across both IMAP
and SMTP submission. If so, then if IMAP session caching is enabled,
no matter how you configure Exim, you can't win, because the IMAP
server and SMTP server don't have an integrated shared session cache!
The only "solution" is for both IMAP and submission to not offer
Mind you, if the submission client just reconnects to negotiate a new
session, rather that continue with a full handshake, and this is all
transparent to the user, then apart from some noise in the logs this
is completely harmless, and you could just leave it the way it is with
IMAP sessions cached (users read a lot more mail then the send).
