your problem is not with ISA, but with the way Exchange IMS works, you will need to locate if Exchange 2000 has one, a filter feature that keys of hotmail name space, I am currently running 5.5 and see no such ability, but then again I forward my mail through a smart host that is responsible for DNS lookups and sending internal mail to the correct SMTP server, this configuration provides a great deal more flexibility with store and forward not to mention it takes those responsibilities away from the Exchange server and eases the work load. I would look at your Exchange server not ISA according to what you wrote below. -----Original Message----- From: Sean Faust [mailto:sfaust@xxxxxxxxxx] Sent: Tuesday, April 22, 2003 2:57 PM To: [ISAserver.org Discussion List] Subject: [isalist] Exchange 2K thru ISA Question http://www.ISAserver.org 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.
