License & Account (*administrator only)
License
In the License page, you can add licenses you have purchased to extend the number limit of the users.
MailPlus Server will automatically sync the status of your licenses with your Synology Account. However, you can also click Sync Now to manually sync your licenses for an immediate check.
Note:
- The operations in this section are only available on the primary server of your mail system.
- Licenses will be installed only on the primary server of your mail system. Once you switch the roles of the servers in your mail system, the installed licenses will be migrated to the new primary server automatically.
- You can log in to your Synology Account in a web browser to check the status of your licenses.
To add a license key to your mail system:
- Click Add.
- To proceed with adding your license key, you must confirm your agreement to the terms and conditions.
- Log in to your Synology account, and make sure the network connection is normal and stable.
- Enter a valid license key. You can click "+" to add more license keys, or click "-" to delete one that you have just entered.
- After you successfully add the license key, MailPlus Server will automatically upgrade the number limit of the users.
Note:
- If your mail system has been detected to match the following conditions:
- Using an illegal license key
- Using expired license keys, resulting in the authorized limit of the users to be outnumbered by the currently activated users
- Activating more users than the authorized limit of the users
- The operations of the MailPlus Server's user interface will be restricted with the security-related services being stopped until you have enough number of valid license keys in your mail system.
