To enhance the security of your SmarterMail installation, you can restrict administrator access to only allow logins from specific IP addresses or IP ranges. This helps prevent unauthorized access and secures your email server environment.
Access the SmarterMail 16 dashboard and log in using your domain administrator credentials.
In the left-hand menu:
Click on Settings
Then select Administrators under the System section.
Click on the administrator username that you want to restrict access for.
Check the box for Restrict login access by IP.
Once enabled, click on the + New Rule option.
Enter the specific IP address or range of IP addresses that should be allowed access.
(Optional) Add a Description for easy identification.
Click OK to add the rule.
After adding the allowed IP address(es), click Save to apply the restrictions.
If you want to allow access only from your office network, enter an IP like 203.0.113.5 or a range like 203.0.113.0/24.
