Oguz,

Can you provide a complete capabilities output that the remote server is
providing (The initial greeting you see when you telnet to port 143)?

The 'unexpected response to auth request' seems to occur after saslauthd
has believed that it has received the initial greeting, has sent the 'login
user pass', and is expecting to receive an OK/NO.

If saslauthd and the imap server happen to be on the same host (and you
don't otherwise need to use saslauthd), you could use 'pwcheck_method:
authdaemond', instead. If you do, you'll need to also provide
an authdaemond_path parameter.
