As a FYI a blog post I did on how to use ISA 2004 to better close your SMTP connection to the outside world … especially when you are connnected to ExchangeDefender.com is up on the ISA server blog
Exchangedefender.com is the service that I use that prefilters, cleans and despams my firm’s email….
Bottom line it makes my email boring these days. And I’m serious about that… it’s quite dull these days. Only business email.
P.S. The post is off the blog site.. sorry if you are looking for it. No, I really won’t go into why it was removed (not for reasons some folks might be thinking of anyway).
