Blacklisting
As a company that uses email services, blacklisting is a scary word. Blacklisting is a listing of a server or IP address on at least one "blacklist." For recipients of emails, these "blacklists" are usually positive because they reduce the likelihood of spam distribution. On the other hand, blacklisting can cause e-mails from legitimate senders to go down. As a user of an IP address, you can be blacklisted for three different reasons:
- A device is infected with a virus and sends spam from your IP address
- If someone emails too many people at the same time
- Someone has given you an IP address that has been used to send spam in the past
Independent e-mail parties create their own blacklists to monitor e-mail traffic. They can set their own rules and conditions when it comes to listings. One of these conditions is the ability to unsubscribe from a blacklist. Usually the listing is gone from the blacklist within 24 to 48.
Is blacklisting preventable?
What can you do to prevent blacklisting? Preventing blacklisting completely is unfortunately not possible, because there will always be a chance, however small, that a mail account or server will be abused. But there are some steps that can be taken to prevent blacklisting. Many users use the same servers. If one of these users suffers abuse, the rest of the users on those servers may suffer as well.
For this, a good spam filter is the solution. For users, it is smart to change passwords more regularly and also not make them too simple. In addition, it is wise not to just open attachments and click on links in received emails. This is because these are the biggest culprits in the world of virus and spam abuse. By being more careful with this, you will prevent your IP address from becoming a victim of blacklisting.
