Anti-Spam

This policy is responsible for evaluating messages for spam based on thresholds and settings you configure to flag items as spam. There are inbound as well as outbound spam policies. Use inbound policies to protect your mailboxes and outbound to protect your domain from being used for spam.

Considerations before deployment

• Are your users used to working with Quarantine items
  • If not it would be a good idea to communicate quarantine to avoid overloading the support desk with calls
• How much bandwidth do you have for releasing messages from quarantine
  • This will determine what action and quarantine policy you might deploy, for example you might make high confidence spam admin only release while allowing users to release less severe spam

Policy Configuration

Depending on the size of your organization it is usually best to create a new custom policy with the highest precedence that you scope to a smaller subset of users such as IT for testing.

The end goal would be removing that policy and having all users protected by the default policy. Only break off custom policies for the few users that have a valid exception.

Policy Types

For Anti-spam policies you have three policy types:

• Inbound spam policies
• Outbound spam policies
• Connection filter policies
