For the past several months I have received a lot of spam. It shows up every day and ALL of it comes from the .INFO domain. I have marked all of it as spam with little success. I have forwarded all of it to firstname.lastname@example.org. That too has been a futile attempt to stop the spam. My suggestion is to add a user option to the spam detector to flag ALL emails from the .info domain as spam. You can control if detected spam is immediately deleted or sent to a spam folder. If you send it to the spam folder you could review emails to determine if too much is being flagged as spam.
