Yes, you can do that, but depending on your
configuration/requirements, you will lose some flexibility - all
connections to Exim through the tunnel will appear from 127.0.0.1, so
you won't be able to ACL based on IP address.

Check your relay configuration carefully, make sure you're not
allowing relay from localhost - instant open relay from the other end
of the tunnel.
