Ok, had some more coffee. This is url blocking in email. Yes, the Ironport is accepting the traffic then blocking it on the machine. Outside hosting of email filtering fixes that if it is an issue for you, but less control over the system. Pick your poison.

Then no, your users request www.BadURL.com<http://www.BadURL.com> and the ironport tells them no right away. It does not fetch the pages and then tell them no. Or is it blocking access to your internal website/systems from bad area's? Then yes, those requests are crossing your pipe to the net. But it is just the request for access, not all of the data. The request gets knocked down before that. If you want it knocked down sooner you need your ISP to do it. From: David W.

I am having bandwidth issues and I see the ironport blocking gigs of requests but I have heard that the data comes into the ironport and gets knocked down there. Well that would have already choked my 3MB line to the Internet. So I am confused if I am actually using the gigs of bandwidth just so ironport can block?? Does this even make sense?? ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
