# Sender to Recipient Block/Allow List

The Sender Checks Bypass permits you to either Block or Allow sender email addresses or sender domains to specific **Internal Recipients** or entire **Relay Domains**. It's important to note that the Sender Checks occur **AFTER** the perimeter checks. For example, if you have setup a sender to be allowed but email is still not coming through, it's possible that the sender's IP address is being blocked by the Hermes SEG perimeter checks.

When setting up a sender email address or domain to be allowed or blocked for an entire Relay Domain within Hermes SEG, the system will automatically create separate mappings for every Internal Recipient for that Relay Domain at the time of setup. However, if additional Internal Recipients are added after the the bypass was set, those Internal Recipients will not get the previously set bypasses. In those cases, you will have to manually add those bypasses for the new Internal Recipients.

### Add Email Address Sender Check Bypass to Internal Recipient

1. Under the **Sender Domain or Email Address ...** field, enter a sender email address.
2. Under the **Select Internal recipient from the ....** drop-down field, select one of the existing **Internal Recipients** in the system.
3. Under the **Select Action to take below** field, select either a **Block** or **Allow** action.
4. Click the **Add** button (**Figure 1**)

5. Each entry you add shows up in the **Block/Allow Sender(s) to be added** section (**Figure 2**).

### Add Email Address Sender Check Bypass to Relay Domain

1. Under the **Sender Domain or Email Address ...** field, enter a sender email address.
2. Under the **Select Internal recipient from the ....** drop-down field, select one of the existing **Relay Domains** in the system. Relay Domains are annotated by a (**@**) at symbol in front of them. For example, if you have a Relay Domain of **mydomain.tld** then it will appear as **@mydomain.tld** in the drop-down field.
3. Under the **Select Action to take below** field, select either a **Block** or **Allow** action.
4. Click the **Add** button (**Figure 4**)

**Figure 4**

5. Since we are mapping an entire **Relay Domain** to a sender, the system will automatically populate the **Block/Allow Sender(s) to be added** section with all the **Internal Recipients** for that domain (**Figure 5**).

### Add Domain Sender Check Bypass to Internal Recipient

1. Under the **Sender Domain or Email Address ...** field, enter a sender domain. If you want to include all the all the sub-domains under a root domain then you would simply enter a (**.**) dot in front of the domain. For example, if you want to include all the sub-domains for **domain.tld**, you would simply enter **.domain.tld** (note the **.** in front of the domain).
2. Under the **Select Internal recipient from the ....** drop-down field, select one of the existing **Internal Recipients** in the system.
3. Under the **Select Action to take below** field, select either a **Block** or **Allow** action.
