Relay Host

Normally, Hermes SEG delivers email directly to remote SMTP hosts over the Internet. Sometimes, this configuration may not work for certain scenarios. For example, your ISP may not allow outbound SMTP over port TCP/25.

In those scenarios it is necessary to configure a Relay Host e.g., an external SMTP host that will receive emails from your Hermes SEG and relay them to their final destination.
