  • Hi Tomas,

    I read from your request that you want to remove the customer's IP from Sophos's RBL blacklist. I'm not 100% sure, but I believe that Sophos is using the RBL lists from Cyren. Check the reputation of the customers IP on their site. Your customer or you, if you are allowed to speak on behalf of your customer, can report the customer's IP address as false\positive here. Cyren needs about 24-72 hours to update the list.

    You are also free to contact Sophos support if you are a Sophos customer and if the first step haven't brought you further or if you need further assistance.

    Good luck to you, stay healthy!
