Your 10-day free trial of the SPAMfighter PRO has expired and you have now been downgraded to the free SPAMfighter Standard.
That means you’ve been limited to only having 5 addresses in your blacklist/ whitelist for example. If you’re using SPAMfighter in a business and/or want more entries, please buy a SPAMfighter PRO license, which can contain the number of addresses you need.
