Sometimes internal users receive external notifications from unknown users via sametime. If the internal user doesn’t know the person and he wants to block it, the only way to do that if he adds the unwanted contact to "The following external contacts are not allowed to see your online status" under Sametime--Privacy.
But what if the internal user keeps receiving notifications, it would put an unnecessary workload on them to add each external contacts by manually.
It would be great to have a master switch to block all external notifications or/and to block domains in sametime client.
For example domain block: “*@microsoft.com" or ability to add wildcard characters to the Name list.
