SMTP Blacklisting Ranking

A spam black list is a list of IP addresses and domains of known spam e-mail servers. Black lists are used to block all e-mail that comes from certain servers on the Internet that have been identified 
What happens if your ISP gets blacklisted?
  • In the best case, your emails will be tagged as [SPAM]
  • In the worst case scenario, your emails will be simply dropped by the remote mailserver without any notification.
