No, it's not an ACL option.

Per my original mail:
: Instead look at setting the mx_domains option on your dnslookup router
: to specify a list of domain-matching items (eg: *.co.com : *.com.com )
: which require an MX record.
If you add:
mx_domains = *
to the dnslookup Router which handles outbound mail, then it will
require an MX record (no fallback to A); the normal recipient
verification in the RCPT ACL will handle this fine, since the domain
should no longer have a Router which accepts mail for it, so the address
will be unhandled.
Exim ships with documentation called The Exim Specification; it's
available online at
www.exim.org or in a file called "spec.txt" which
your software packages should have installed somewhere. In that, you
can search for "mx_domains" to get more detailed information.
