I am currently blocking hotmail thru the web proxy service. I have Exchange2K published thru the ISA server, when a user goes to send mail to hotmail with the site blocked the messages sit in the queue on the Exchange server, when I stop blocking hotmail.com the messages go thru. Is this by design or am I missing something? I will swear that this just started today.
