# Relay IPs & Networks In this section, you can add which individual IPs or networks will be allowed to send (relay) email through Hermes SEG. **Best security practice is to never allow entire networks to send email through Hermes SEG and instead only allow specific IPs.** ### Add Relay IP 1.

Under the **Note** field, enter a note identifiying the IP address and click the **Add** button (**Figure 1**). **Figure 1** [![image-1606159291850.png](https://docs.deeztek.com/uploads/images/gallery/2020-11/scaled-1680-/image-1606159291850.png)](https://docs.deeztek.com/uploads/images/gallery/2020-11/image-1606159291850.png) 4.
