Definition
The Return-Path, or envelope sender, receives bounces and delivery notifications. It is hidden from recipients and can differ from the From address.
Because authentication runs against the Return-Path, it must be configured and monitored.
The Return-Path domain is where delivery feedback arrives, giving early warning of bounces and reputation problems. A dedicated domain keeps that feedback separate from your brand. Configuring SPF for it ensures notifications are accepted.
Why It Matters
Bounces and delivery reports flow to the Return-Path.
A dedicated Return-Path isolates reputation.
Best Practices
- Monitor your return-path mailbox for delivery notifications.
- Ensure the return-path domain is authenticated.
- Use a dedicated domain for Return-Path to protect your brand.
- Monitor the Return-Path mailbox for bounces and delivery notifications.
- Publish SPF for the Return-Path domain.
- Use a dedicated domain for the Return-Path to protect your brand.
- Process bounces automatically.
