Spammers are always looking for doorways to send spam emails. If your exchange server is an open relay which can easily help spammers to pass through, then many mail servers and ISPs will blacklist your domain. When you find out that your domain is blacklisted, you should take steps in removing your domain from that list so that your subscribers can receive your mail without fail. However, finding whether your domain is in the blacklist is the tricky part here and it can't be done without a proper tracking tool.

Spammers use spoofing to conceal their original identity. When your ip address or domain is used by spammers consistently to send out emails, then it is obvious that mail servers will consider your ip address and domain to be a spam. Popular domains are also commonly used for spoofing, but since the servers are aware of those domains, the whole domain will not be blacklisted. When your less known domain is in blacklist sites, mail servers will immediately blacklist the whole domain.

The only way to pass blacklist test is when you have your domain name is in the whitelist. Mail servers update their blacklist sites from time to time. When you contact the mail servers and prove them that your domain is not a spam, then you can whitelist your exchange server. However, after whitelisting, you should follow procedures to prevent spammers from using your exchange server to send spam emails.

Knowing domain is blacklisted is very crucial to take the next course of action. A proper mail monitoring and tracking tool which ensures email deliverability will check your domains and ip addresses against major blacklists popularly used by mail servers. All your emails will be tested against blacklists and any dispute will be reported to you. With this report, you can take steps to whitelist your domain to get in touch with your subscribers.
