Spam Ignorer is a powerful antispam system designed to protect your mail server from spam with 100% of effectiveness and in a simple way. Spam Ignorer checks and validates the origin of the messages, to ascertain whether the senders are included in the valid sender lists (White List). Any sender not listed on the white list will receive a validation message. Just by replying it, the sender will be added to the white list and all sender?s messages will be automatically delivered. Spam Ignorer will remember the sender in the future. Additionally you have a black list to add the addresses of who you don't want to receive mail (spam).
