How does my SPAM Web App work?
When a message is being received, it is either determined to be SPAM—and discarded—or clean mail—and delivered to your inbox.

Are there different settings for my SPAM Web App?
Yes. When you choose "high," "medium," or "low" for your SPAM setting, a filter is created on your account, which will be labeled based on your preferences. When you choose another SPAM setting, your original preference will be replaced with the new one. If you choose "none," the filter will be removed altogether.

Why does it appear that my SPAM Web App isn't working?
SPAM Web App is very efficient at removing unwanted SPAM, making it seem as if it may not be working. Although it may appear this way, it is actually removing SPAM behind the scenes so that it never is visible in your inbox.
