That is cheap if you factor in the man hours spent maintaining in house systems, the cost of the systems themselves, and the wasted bandwidth! Plus it isn't just an anti-virus system, it also does monitoring, load balancing, notifications, spam filtering, e-mail bomb filtering, and dictionary attack filtering. I think if you add the cost of doing all of that in house, your cost is going to be much higher than 3,600/year. >... in exchange for a third party having access to your E-mail, and adding >an extra point (albeit likely very secure) for unauthorized access to the >E-mail. This is a pretty misguided statement considering the insecure nature of e-mail anyway. Anyone truly worried about mail security will use pgp, or some other type of encryption device along with digital signatures. And as for the "extra hop" ??? The Postini service adds about an extra 80 milliseconds to the delivery time of an e-mail. I don't think a companies customers are going to be up in arms about the slow mail system over this one. More likely, the in house systems (running declude, etc.) are going to delay mail more than the postini system. Their systems are dedicated to 1 process, not 10 like most corporate mail systems(listsrv,www mail, virus scanning, spam filtering, pop3 traffic, etc.)) Jason Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
