Find out if you have been blacklisted
Blacklists (also known as Domain Name Server Black Lists or DNSBL) are lists of suspect IP addresses or domain names maintained by major receiving mail servers.
Most mail servers use more than one blacklist to block suspected spammers from sending unsolicited email. They can block spam sent directly to them, or spam sent from them (if spammers try to use their servers as "relays" to send mail indirectly).
To find out if you have been blacklisted by one of the common blacklists, enter your mail server's domain name and IP address below.
