Nick: I recall a lot of discussion about this with Blackice firewall installed on the IMail machine.
It seems like a lot of people had a good experience with dictionary attacks being blocked by Blackice. May be it is not bad to revisit that discussion.

In the magnitude of over 1 million emails a day :) [Won't be long before these attacks come your way... ] We are using orf with a recipient blacklist to filter the traffic and it is working like a charm. To take this a step further I would like to create an dnsbl that would contain valid email addresses that ms smtp, orf and DJM - but more importantly ms smtp could use and reject on. Has anyone seen or know of a way to do this?
