[Exim] Forcing authenticated connections over TLS

Folks,

I'm trying to set up an ACL which does this for all authenticated connections. I've set up an acl_smtp_auth procedure as in the manual i.e.

acl_check_auth:

accept encrypted = *
deny message = TLS encryption required

This works in that the error message appears in the main log but the following acl_check_rcpt ACL allows the connection anyway. How do I prevent the acl_check_rcpt from being run if acl_check_auth has rejected the connection? Sorry if I'm missing something obvious here.

Thanks,

Clive McDowell
