Are there any guidelines for publishing McAfee Quarantine Manager externally? As users are self registiered, how would authentication take place from external?
I can't find a reference to it in any of the documentation I have handy, but the general recommendation for publishing it exernally is not to do it. I can not think of a scenario where you would be sending an outbound message and actually want the recipient to control if they receive it or not. If you have a policy that blocks the message then an administrator should be looking to see if the message should be delivered (and if the policy should be changed).
