Backup MX: queue and delivery
Keep primary MX records and add the less-preferred SecuraWall MX. Mail received through this route waits while the destination is unavailable and is delivered on recovery. No antivirus, spam, content inspection or quarantine is applied.
Email Protection: add protection
Email Protection includes queuing and delivery retries, with SecuraWall as the only published MX. Save and verify the real server as a manual delivery target before removing other MX records. Enabled spam, antivirus, identity and content policies plus quarantine apply to gateway traffic. Direct delivery to your real server can still bypass the gateway unless that server restricts it.
SMTP Relay: add sending
SMTP Relay is a separately paid add-on for an active Package 1 or 2 on the same domain. Approval, an enabled device account and authorized sender domains are required. Verify sender SPF before payment. Customer DKIM signing is optional and recommended.
Changing packages
Choose base Package 1 or 2 per domain. SMTP Relay is an optional add-on, not an upgrade of the base. Choose any higher package during the active period without an immediate charge; the next renewal uses its monthly price. Changes to any lower package and cancellation take effect at the paid period end. Remove outbound client routes before discontinuing SMTP Relay.
