If I unplug that cable they have no Internet. I don't control the firewall anymore, only on each system itself via OS. Unplugging Internet is doable if I have to really, but then I can't test workstation logins from their "remote site" (it's on the same VLAN, but in a physically different location) before flipping mail on.
I also don't have access to the Barracuda either :-( Eh, worst case is I unplug the damn thing.

Exchange and Windows use SMTP for their own internal purposes, so just shutting down the SMTP service is likely a bad idea. I think you would need to create a connector and then fiddle with that. You'd have to be careful not to turn it into a permanent failure, though, or the mail will never deliver. So simply denying senders wouldn't work. I am not sure. > Last time I simply unplugged the Internet connection but there has to > be a better way. What's the problem with this approach? It's simple, reliable, easy. If you don't want to loose all Internet connectivity, just block TCP port 25 on the firewall. > They do have a Barraccuda 300 in front and I am tempted to just point > it to a nonexistent Exchange server but I don't want the messages to > bounce, I just want them to queue up. If you point it at a non-existent IP address, it should see that as "host down" and queue (assuming it can queue). It may start sending warning notices back to the senders about temporary failure to deliver, though. -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin
