Watchguard Network Security Practice Test

Which option is configured for outgoing SMTP traffic in the SMTP proxy action settings?

1. Rewrite the Mail From header for a specific domain.

2. Deny incoming mail from a specific domain.

3. Prevent mail relay for a specific domain.

4. Deny outgoing mail from a specific domain.

The correct answer is: Rewrite the Mail From header for a specific domain.

The correct choice involves configuring the SMTP proxy action settings to rewrite the Mail From header for a specific domain. This functionality is essential for managing email traffic effectively. It allows organizations to modify the sender's address in outgoing emails to match policies or branding requirements without altering the actual sender's address on the client's side. In scenarios where an organization may be using different domains for different divisions or subsidiaries, rewriting the Mail From header ensures that emails are presented to recipients in a consistent manner, thereby enhancing the brand image and improving deliverability. This adjustment can facilitate compliance with various regulations while controlling the information that is visible to external entities. The impact of this feature highlights an important aspect of email management, specifically how SMTP proxy services optimize email handling and ensure that communication aligns with the organization’s external representation and policies. This capability is particularly useful in scenarios where domain authentication practices such as SPF (Sender Policy Framework) might need to be aligned with the headers to avoid delivery issues.
