You need to configure Exim to announce AUTH. Exim does not against what
you want to authenticate. For using Exim with Courier-IMAP, see

You always need authentication in Courier-IMAP, it needs to know which
user wants to access his mail. In Exim, you need it e.g. if you want to
allow remote user to use your mail server as a relay.

pop/imap are protocols for users to download their mail. smtp is for
delivering mail to a mail server. From a MUA's view, they are protocols
for the same service, but different directions.
