# System Settings - The **Postmaster E-mail Address** MUST BE on a domain that the system currently delivers email for and the **Admin E-mail Address** SHOULD BE an email address for a domain that Hermes SEG does NOT deliver email for. Even though the system will allow you to enter an Admin E-mail Address for a domain that Hermes SEG deliver email for, it's not recommended. The **Admin E-mail Address** should be an external to the system e-mail address. - The system will automatically create virtual addresses for **postmaster**, **abuse** and **root** based on the **Postmaster E-mail Address** you set. For example, if your Postmaster E-mail Address is **postmaster@domain.tld** and your Admin E-mail Address is **someone@otherdomain.tld**, the system will automatically create the following virtual address: - **postmaster@domain.tld** ---> **someone@otherdomain.tld** - The system will also create the following two virtual addresses and related mappings based on the postmaster e-mail address domain part: - **abuse@domain.tld** ---> **someone@otherdomain.tld** - **root@domain.tld** ---> **someone@otherdomain.tld** - The virtual address the system creates can be viewed under **Gateway ---> Virtual Recipients**. - Adding a Serial Number is not required. However, if you are going to add a Serial Number, ensure Hermes SEG has access to the Internet over ports **TCP/80** and **TCP/443**. Serial Numbers are validated over the Internet with our activation service). - If you have a Serial Number, click the **Add Serial Number** button and in the resultant window enter it in the **Serial Number** field, check the license convert checkbox and click the **Submit** button (**Figure 1**). **Figure 1** [![image-1656410867375.png](https://docs.deeztek.com/uploads/images/gallery/2022-06/scaled-1680-/image-1656410867375.png)](https://docs.deeztek.com/uploads/images/gallery/2022-06/image-1656410867375.png) - In the **Postmaster E-mail Address** field enter the email address you want to use - In the **Admin E-mail Address** field enter the email address you want to use - In the **TimeZone** field, set your local timezone by deleting the default **America/New\_York** and start typing the name of your continent. The system will automatically display a drop-down with all the relevant timezones for your continent (**Figure 2**). **Figure 2** [![image-1656411073214.png](https://docs.deeztek.com/uploads/images/gallery/2022-06/scaled-1680-/image-1656411073214.png)](https://docs.deeztek.com/uploads/images/gallery/2022-06/image-1656411073214.png) - If you have activated a Hermes SEG Pro Serial Number, the **Daily Update Check** field will be available for you to **Enable/Disable**. If you enable the **Daily Update Check**, the system will automatically check for Hermes SEG updates on a daily basis and if it finds one, it will send an e-mail to the postmaster E-mail Address you set above. - In the **Telemetry** field, set to **Enabled** (By default it's enabled) if you wish to allow the sending of anonymized data to our servers in order to improve Hermes SEG and our services. **Rest assured, that we do NOT share or sell this data and it's strictly used for internal purposes**.
