Email Forwarding

Privacy

Automatic redirection of inbound mail from one address/mailbox to another; often used for aliasing.

Definition

Email forwarding routes messages based on rules (address-level forwarding, catch-all, filters). Privacy depends on who can read mail at each hop and whether forwarding preserves headers that reveal identity.

In plain English Automatic redirection of inbound mail from one address/mailbox to another; often used for aliasing.

Why this matters

Why it matters: Forwarding enables per-service aliasing and containment of breaches, but can introduce additional metadata exposure if a third party handles the routing.

Example

Example: Use a forwarding provider to generate unique aliases per service and disable an alias when it starts receiving spam or appears in a breach.
