This functionality is available in the SMTP accounts tab > Settings. It allows you to restrict access to your SMTP server for a specific IP address or a group of IP addresses. As a result, it improves the security level of the server-server communication even if your password gets leaked.
- 1.To enable this option, check the “Turned on” box.
- 2.Enter the IP address or mask you want to restrict access for.
- 3.First, click the “Add” button and then “Create” to save the configuration.
Important! Make sure to enter the correct IP addresses or subnet masks. Incorrect configuration can lead to losing access to the SMTP server. We also recommend regularly looking through the authorized IP addresses and updating them.
