How inbox replies work

Run2Mail can send a real outbound reply from an inbox message view when the feature is enabled by the administrator. The reply flow is designed to stay lightweight and safe while preserving the existing inbox experience.

• The Reply action is feature-gated and can be enabled or disabled from admin settings.
• Replies use the configured Laravel mail transport for actual delivery.
• Outbound attempts are logged for diagnostics and troubleshooting.

Operational modes

• Simple Send Mode
• Safe Subject Mode
• Threading Headers
• SMTP Delivery

Simple Send Mode

Sends a clean plain-text email with minimal mail customization. This is the safest mode when validating delivery before advanced threading behavior.

Safe Subject Mode

Uses a predictable subject to reduce the chance of provider-side filtering while the reply pipeline is being verified.

Threading Headers

When enabled, Run2Mail can attach message identifiers and references to improve threading behavior in clients such as Gmail and Outlook.
