Do you mean something like this?
acl_smtp_auth = check_security
[...]
###########################################
# ACL that is used after the AUTH command #

check_security:

accept encrypted = *
deny message = Encryption required for authenticated sending.
I don't see a single instance of this message triggered in our entire
archived logs, so it looks as if clients are behaving correctly, in
accordance with the fact that we're only advertising auth when TLS is
in effect.
