Ahhh, the sweet smell of validation at last! :) That's it, that what kicked my network into the ole blackhole back then! - Thanx! Karyn. Karyn Ulriksen wrote:

What I was saying is that they had already set up some type of blackhole system that I was lead to believe they were doing at the router level (not mail system level).

I know your next thougt is that they just threw us into their route filter, but my understanding is that they offered a service that you subscribed to and the updated the filter on the fly.
