To address spoofed emails you can create a policy for filtering spoofed e-mail messages from the same domain as recipients. Normal spoofed e-mail messages spoof the recipient domain. Please note best practice is to have internal e-mail messages not be routed out of the Internet or through TMEMS. Create a policy to filter e-mail messages coming from your own domain.

1. On your browser, login to Trend Micro Email Security administrator console.
2. Go to Inbound Protection > Content Filtering, then click Add.
3. Type name of the rule you are creating (e.g. Anti-Spoof Policy).
4. Go to Recipients and Senders > Recipients, then add your domain.
