If they are this badly behaved there's not much you can do with
exim. You can try just dropping the connection in the ACL given by
acl_smtp_connect. Or deny them access in /etc/hosts.allow if you've
compiled exim with tcpwrapper support. However you'll still see all
the attempted connections. Probably the best place is to configure
your firewall to deny them access. Then exim won't even see the
connections.
