Pretty easy to do and even to write yourself in CF (+ a telnet component). Query your email database, group by domain names. Then do a nslookup for the MX record. Connect to it using telnet, do a HELO, followed by a MAIl FROM and then a RCPT TO for each emailaddress in that domain. 5xx errors are permanent and you should remove the addresses from your database. End with a QUIT. I do it manually all the time to verify email addresses when I hunt spammers. >If I were a postmaster, I think that I would be in favor of some sort of >coop cleaning routine among honest (non-spamming) marketers, say once >per month?!?!? No. Only makes it harder to find the spammers doing a dictionary probe because the logfiles are larger. I would prefer the sending mail server to be smart enough to remove people when sending normal mail, instead of having to probe for it.
