The Register has some details about MessageLabs. About $.66/user/month for spam scanning, about $2.20/user/month for virus scanning. MessageLabs claims they have over 500,000 users, so that gives a revenue estimate of at least a million dollars a month. Not so bad, although I bet their operations are expensive. I wonder how well their service really works? There's a lot of value in centralizing this kind of filtering.
