# 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 **Select the type of entry...** section, Select **IP Address** option.
2. Under the **IP** field, enter the IP Address that you want to allow.
3. Under the **Note** field, enter a note identifiying the IP address and click the **Add** button (**Figure 1**).

4. Each IP address you add shows up in the **Permitted Relay IPs/Network to be added** section (**Figure 2**)
