I have a request from my BOE office group wondered if there is a way to manage the Trust/Block list for the end users. They have a few addresses that they requested people add to the Trust list which isn't getting done. They wanted me to added it for them. In the past this couldn't be done without special software added to the system.

Has this changed any?
If it is manageable with 3rd party tools, what would that be? Is it expensive?

We are a smaller school system so I am looking at 250-300 address roughly to manage.
