I want to block any connection that doesn't have a successful rDNS (logs
report "no host name found") but searching around results in so many
different variants of an ACL rule to do this.
I've got following in acl_check_rcpt (because I want to log/see the sender
and recipient):
# deny hosts without reverse mapping
deny hosts = !+relay_from_hosts
!authenticated = *
message = Reverse DNS lookup failed for host
$sender_host_address.
!verify = reverse_host_lookup
