Select or clear the Detect spam checkbox to enable or disable this protection.
The available actions are:
The tag Spam will be added to the subject line of messages let through. This is the default option.

What is SCL? (More information)
Use the Add, Delete and Clear buttons to configure a list of addresses and domains whose messages will not be scanned by the anti-spam protection (whitelist), or a list of addresses and domains whose messages will always be intercepted and deleted by the protection (blacklist).
Add: Use this button to select, one by one, the email addresses and/or domains to add to the list.
Delete: Use this button to delete addresses/domains.
Clear: Use this button to clear the whole list.
Keep in mind the following aspects when configuring these lists:
If a domain is on the blacklist but an address in the domain is on the whitelist, the address will be allowed. However, all other addresses in the domain will be blocked.
If a domain is on the whitelist but an address in the domain is on the blacklist, that address will be blocked. However, all other addresses in the domain will be allowed.
If a domain (e.g.: domain.com) is on the blacklist and one of its subdomains (e.g.: mail1.domain.com) is on the whitelist, the addresses in the subdomain will be allowed. However, all other addresses in the domain or in any other of its subdomains will be blocked.
If a domain is on the whitelist, all subdomains in the domain will also be whitelisted.
