Summary
Email Relay is an e-mail store-and-forward message transfer agent and proxy server. The service does three things:
- Stores any incoming e-mail messages that it receives
- Forwards e-mail messages on to another remote e-mail server
- Serves up stored e-mail messages to local e-mail reader programs
More technically, it acts as a SMTP storage daemon, a SMTP forwarding agent, and a POP3 server.
This manual page provides an overview of the Email Relay functionality in {{{name}}} devices.
Note: Email Relay is additional software that can be installed from the System → [[{{{name}}} Package Manager|Package Manager]] page.
