Configuring the global block and safe list
The System tab lets you configure system-wide block and safe lists to block or allow email by sender. It also lets you back up and restore the system-wide block and safe lists.
| You can alternatively back up all system-wide, per-domain, and per-user block and safe lists together. For details, see “Backup and restore”. |
| Use block and safe lists with caution. They are simple and efficient tools for fighting spam and enhancing performance, but can also cause false positives and false negatives if not used carefully. For example, a safe list entry of *.edu would allow all email from the .edu top level domain to bypass the FortiMail unit's other antispam scans. |
To access this part of the web UI, your administrator account’s access profile must have
Read or
Read-Write permission to the
Block/Safe List category. For details, see
“About administrator account permissions and domains”.
| Domain administrators can access the global block list and global safe list, and therefore could affect domains other than their own. If you do not want to permit this, do not provide Read-Write permission to the Block/Safe List category in domain administrators’ access profile. |
To view the global block list or safe list, go to AntiSpam > Block/Safe List > System. The page displays two links:
• Block List
• Safe List
