I'm looking software that will allow us to scan our own netblocks for open smtp relays and open http and socks proxies. The spammers are very aggressive about abusing these systems and we want to check to make sure our users aren't running such vulnerable systems. I know rlytest in the ports collection checks one host for smtp relaying, but I'd like to scan entire netblocks at once. What else can be done to keep user's systems safe from spammers?
