I would not recommend this, and I believe, Exim should fallback to
Non-TLS anyway, if setting up the encrypted connection does not work.

Are there other TLS related settings in your config?

I'm not sure how recent OpenSSL 0.98e is.

I do not see why Exim should reject STARTTLS. Maybe it would do so, if
the tls_advertise_hosts main config option is empty or doesn't match the
current connection.

Do you have more output from the logs?
