Set System Certificates

Navigate to System --> System Certificates (New Web GUI).

Hermes SEG Community Version

Hermes SEG Community Version will allow you to create Certificate Signing Requests to submit to 3rd party CAs and import certificates from 3rd party CAs.

Click the Import Certificate button, enter a friendly name for the certificate in the Certificate Name field, paste the contents of the certificate including the -----BEGIN CERTIFICATE----- & -----END CERTIFICATE----- lines in the Certificate field, paste the contents of the unencrypted key including the -----BEGIN PRIVATE KEY----- & -----END PRIVATE KEY----- lines in the Unencrypted Key field, paste the contents of the root and Intermediate CA certificates including the -----BEGIN CERTIFICATE----- & -----END CERTIFICATE----- lines in the Root and Intermediate CA Certificates field and click the Import button (Figure 3):

Figure 3

Hermes SEG Pro Version

Hermes SEG Pro Version will allow you to create Certificate Signing Requests to submit to 3rd party CAs, import certificates from 3rd party CAs as well as Request Lets Encrypt (Acme) Certificates.

If you wish to import a 3rd party CA certificate, please follow the Hermes SEG Community instructions above to import a certificate. If you wish to request a Lets Encrypt (Acme) certificate, follow the instructions below:

Before requesting Acme Certificates ensure that BOTH ports TCP 80 and TCP 443 are open to Hermes SEG from the Internet and the domain you are requesting the certificate is pointing to the Internet accessible IP address of your Hermes SEG machine. We recommend that you test using the Acme Staging server first to ensure the request works before attempting to use Acme Production. The reason we initially Request Acme Certificate utilizing the Acme Staging server is because Lets Encrypt is much more lenient with rate limits with failed requests in their staging environment than their production environment, click here for details.

Click the Request Acme Certificate button, enter a friendly name in the Certificate Name field, enter the FQDN (domain name) you wish to request a certificate, enter a valid e-mail address in the Notifications E-mail address field, leave the Acme Server drop-down field set to Acme Staging and click the Request button (Figure 4):

Figure 4

If the Acme Certificate Request fails, double-check that the FQDN (domain name) points to the Internet accessible IP of your Hermes SEG machine and that BOTH ports TCP/80 (HTTP) and TCP/443 (HTTPS) are allowed through your firewall and try again.
If the Acme Certificate Request succeeds, locate the newly created certificate in your certificate list, click the icon and on the resultant Delete Certificate confirmation click on Yes (Figure 5):

Figure 5

Click the Request Acme Certificate button again, enter a friendly name in the Certificate Name field, enter the FQDN (domain name) you wish to request a certificate, enter a valid e-mail address in the Notifications E-mail address field, this time set the Acme Server drop-down field set to Acme Production and click the Request button (Figure 6):

Figure 6

Set Console Settings

The Hermes SEG Console Settings sets the method you wish to access Hermes SEG machine which includes the Admin Console, User Console and the Ciphermail Console. By default, the Console Mode is set to IP Address, however, an IP address is not contusive to using SSL certificates. Therefore, if you plan to use a SSL certificate to access the Hermes SEG machine, you must set the Console Mode to Host Name. The Host Name you set it does NOT necessarily have to the the same Host Name you set in Network Settings above. The Host Name you set in the Network settings is used for SMTP transactions such as SMTP TLS and it's not related to Hermes SEG console access.

Navigate to System --> Console Settings (New Web GUI).
Set the Console Mode drop-down to Host Name and in the resultant Host Name field that appears, fill in the desired host anem you wish to use (Figure 7):

Figure 7

The Console Certificate field is pre-populated with the system-self-signed certificate. If you wish to use a SSL certificate you set in the Set System Certificates section above, simply delete the system-self-signed entry and start typing the friendly name of the certificate you setup previously that matches the host name. The system will locate the certificate and display it in a drop-down list. Click on the certificate and the system will automatically populate all the rest of the Certificate fields such as the Subject, Issuer, Serial and Type (Figure 8):

Figure 8

Figure 9

After clicking the Submit button and you changed the Console Mode from IP Address to Host Name, your browser will NOT automatically redirect you to the new console address. Ensure you enter the new address in your browser as https://<HOST_NAME>/admin/ where <HOST-NAME> is the new Host Name you set above.

Additionally, we recommend that you generate a DH (Diffie-Hellman) Parameters file by clicking the Generate DH Parameters File button and on the resultant Generate Diffie-Hellman (DH) Parameters File confirmation window, click on Yes (Figure 10):

Figure 10

Generating a DH Parameters file can take a very long time to complete (~40 minutes on 1-CPU systems). You can proceed to configure the rest of your system (DO NOT reboot the system while it's generate a DH Parameters file) and check back under System --> Console Settings to see if a new Diffie-Hellman (DH) key-exchange drop-down appears set it to Enable and click the Submit button below (Figure 11).

Figure 11

If you follow the above recommendations, you should be able to achive an A+ rating on the Qualys SSL Labs SSL Server Test (Figure 12):

Figure 12

Set SMTP TLS Settings

It's important to set SMTP TLS in order to transmit e-mail messages between your Hermes SEG machine and other e-mail servers with TLS encryption.

Before you can set SMTP TLS, you must first have either imported or requested a SSL Certificate in the Set System Certificates section above for the Host Name you set in the Set Network Settings above.

Navigate to Gateway --> SMTP TLS Settings (New Web GUI).
Set the SMTP TLS Mode drop-down to Opportunistic TLS.
The SMTP TLS Certificate field is pre-populated with the system-self-signed certificate. If you wish to use a SSL certificate you set in the Set System Certificates section above, simply delete the system-self-signed entry and start typing the friendly name of the certificate you setup previously that matches the host name you set in the Set Network Settings above. The system will locate the certificate and display it in a drop-down list. Click on the certificate and the system will automatically populate all the rest of the Certificate fields such as the Subject, Issuer, Serial and Type (Figure 13):

Set Relay Domains

In order for Hermes SEG to deliver email, you must first set the domain(s) that Hermes SEG will process email for along with their corresponding email server(s). You can add as many domains and email servers as required. An email server can be configured as an IP address or a Host Name as long as the Hermes SEG can reach it over Port TCP/25. Multiple domains can be pointed to the same email server if necessary.

If you are in the new Web GUI, click on the Old Web GUI link on top of the screen (Figure 19):

Figure 19

Navigate to Gateway --> Relay Domains (Old Web GUI).
Under the Relay Domain Destination Type, select whether you are adding an IP Address Destination to an email server or a Host Name Destination to an email server.

If you are adding an IP Address Destination

In the Relay Domain field enter the domain name, in the IP field enter the email server's IP address, in the Port field enter the email server's port number (if other than 25) and click the Add button (Figure 20).

Figure 21

If you are adding a Host Name Destination

In the Relay Domain field enter the domain name, in the Host field, enter the email server's Host Name part of the FQDN address (without the domain part), in the Domain field, enter the email server's domain part of the FQDN address, in the Port field enter the email server's port number (if other than 25), check the MX Lookup checkbox if necessary and then click the Add button (Figure 22).

Click the Save Settings button.

Set Relay IPs & Networks

In addition to inbound email, if the email server(s) you added will also be sending outbound email through the Hermes SEG (recommended), you must allow their IP address(es) to send (relay) email through the Hermes SEG.

Navigate to Gateway --> Relay IPs & Networks (Old Web GUI).
Ensure IP Address is selected and the under the IP Address field enter the IP Address of the email server that you want to allow to send email through the Hermes SEG, under the Note field, enter a short description identifying the email server (ensure that you don't use any spaces or special characters in the Note field) and click the Add button (Figure 23)

Figure 23

Repeat as necessary for every email server that you want to allow to send outbound email through the Hermes SEG.
As you add entries, you will notice that each entry shows up under the Permitted Relay Ips/Networks to be added section (Figure 24)
