Doing it on 'ethernet' is far different from doing it on T1 over ATM or channelized oc-48... A Checkpoint FW can do this sort of thing with a 'security server' (though performance is certainly a question...). I think you're also always stuck in a store-and-forward mode so 'on the wire' isn't really helpful for SMTP, often you can't make a decision about an email without getting a large portion of it down, so snuffing connections mid-stream isn't going to help your email infra very much :( -Chris > Frank > > -----Original Message----- > From: Ken Simpson [mailto:[email protected]] > Sent: Monday, June 23, 2008 5:23 PM > To: [email protected] > Subject: Re: Cloud service [was: RE: EC2 and GAE means end of ip > addressreputation industry?
