Clark SpamBlocker White/Black List

Here you can add and remove users from your whitelist and blacklist. As the name suggests, addresses on the whitelist will always go through, addresses on the blacklist will never go through.

Note many spam messages can appear to be sent from an @clarku.edu email address and if you whitelist @clarku.edu emails, all of those spam messages will end up in your inbox. We strongly recommend against whitelisting @clarku.edu or any other domain.

You can also edit domains already on the list by changing the position of the dot within the chart to the according option and clicking update.
