Advanced Techniques: Securing Smarter Mail with SSL/TLS Encryption

SSL and TLS are secure protocols that enable encrypted data transmission, enabling users to access email through third-party clients without fear of data interception. SSL encrypts connections immediately, while TLS is encrypted after the STARTTLS command. TLS is set up on ports 25, 110, and 143.

Note: This article assumes that you have obtained an SSL certificate from your provider and installed it in the server’s certificate store personal folder. If not, follow the instructions below.

a) How do I export my SSL certificate to a PFX certificate file in Smarter Mail?

1. First, open the Microsoft Management Console (MMC).

2. Then, CTRL + M to add new Snap In -> Certificates -> Select Local Computer.

3. After that, expand Personal.

4. Then, expand the certificates.

5. After that, right-click the required certificate, select “All Tasks” and then “Export“.

6. Next, click Next in the new window that pops up.

7. Then, select Yes, export the private key, and click Next.

8. After that, enter the required password and click Next.

9. Next, select Personal Information Exchange PKCS #12 (PFX) and ensure all certificates are included in the certification path, if possible, and then click Next.

10. Finally, specify the path and name to save a certificate, like C:\SmarterMail\Certificates\mail.domain.com.pfx, and click finish.

b) How do I add a port to listen over SSL or TLS in Smarter Mail?

1. First, log into Smarter Mail as an administrator.

2. Then, click on the Settings icon.

3. After that, navigate to Bindings in the navigation panel to access the Ports tab.

4. Next, click New in the content pane.

5. Then, fill in the following required fields: protocol, encryption (SSL or TLS), name, port, certification path, and password. All other fields are optional.

6. After that, choose the desired IP address of the port to listen to.

7. Finally, click Save.

Note: The process involves modifying standard ports like 25, 110, and 143 to use SSL or TLS encryption, following the same steps as before.
