Am receiving a flood of emails that appear to emanate from Servers who have received spam that has masqueraded root@mydomain as the email source. Could anyone please suggest the best way of dealing with these. Please bear in mind I am not all that familiar with postfix so if anyone feels treating me like an idiot and spoonfeeding the actual command s to use I would be most appreciative I have just installed procmail but not yet activated it. (Incidentally I do have a number of virtual domains but the only one that seems to get flooded is the primary hostname. There have also been numerous failed hacking attempts on to the system but as they keep trying to get in using services that are not actually running they have got nowhere (so far!!) david
