Are you using the valid rcpt to check in greyscanner, when tied with disposable addresses, it is very effective atleast with informed users. I have a perl script or two that reads my smtpd configuration files and works out valid recipients from that but I started with a simple list of perl regex. Also it is easy to knock up a script using spamdb and dig to check dnsbls like barracudas, couple it with unbound as a caching resolver. Let me know if you need help with that? -- KISSIS - Keep It Simple So It's Securable
