Default email malware policies are enabled by default. When you create a new email malware policy, it is enabled by default. You can disable any policy that you do not want Symantec Messaging Gateway to use when it scans email messages.
You can disable a malware policy to troubleshoot email malware scanning issues. You can also create custom email malware policies when an outbreak occurs and then disable the policies when the outbreak ends. You can turn on the policy in the event of another outbreak.
You can also disable the policies that you no longer want to use but do not want to delete yet.
To enable or disable email malware policies
In the Control Center, click Malware > Policies > Email.
Check the box beside the policy that you want to enable or disable.
Click one of the following options:
When you enable a policy, a green check mark appears in the Enabled column.
When you disable a policy, a horizontal line appears in the Enabled column.
