More worrying about spam stuff. The Sophos product looks pretty nifty, but price could be a real factor there. Cyphertrust also looks pretty nifty, but the apparent lack of an end-user definable white-list could scuttle that one. Postini came in way over budget. NAI just as out of budget and with a third of the functionality as the rest of 'em.

We just threw a sniffer onto the network in the hopes of catching the traffic that causes the apache dump.
