FortiMail Best Practices: System Maintenance

Although your FortiMail unit will catch almost all threats that are sent to your network, there are some things you should be aware of if you want to maximize security. 

The Best Practices recipes will cover specific tips to ensure the most secure and reliable operation of your FortiMail unit.

This recipe covers the best practices for system maintenance.


System Maintenance Tips

The following are some tips to keep your system running smoothly.

1. Before you upgrade or downgrade any firmware, always perform a complete backup of configurations files and other related data, such as the Bayesian database, dictionary, and black and white lists. 

For details on how to perform a complete backup, see the corresponding chapter in the FortiMail Administrator Guide.

2.  Always keep your firmware updated.  Go to Monitor > System Status > Status and select the Update link from the FIrmware Version row. Make sure to back up the configuration data before updating.

3. Configure the FortiMail unit to accept both scheduled and push updates of antivirus attack definitions. FortiGuard updates are configured in Maintenance > FortiGuard > Update.
4. Before a FortiMail unit can receive FortiGuard Antivirus and/or FortiGUard Antispam updates, it needs to connect to the FortiGuard Distribution Network (FDN). FDN connection status can be checked in Maintenance > FortiGuard > Update.
5. Allow the FortiMail unit access to a valid DNS server. DNS services are required for many FortiMail features, including scheduled updates and FortiGuard Antispam rating queries. The DNS server used by the FortiMail unit is configured in System > Network > DNS.
