DNSBLs and RBLs are generally used on email servers to reject or flag email which is sent from an email server has been Blacklisted. Same to our email hosting, RBLs are the basic antispam features.
If your email server IP address has been blacklisted in the DNSBL’s database, the emails sent will be rejected or identified as SPAM. Likewise, we use these lists to classify an email as a spam email.
Our IP Reputation Protection System queries major DNS-based Blackhole List databases and SenderBase which is one of the world’s largest email and web traffic monitoring network, and process these results to send alerts to our support team to take immediate action in the event of any of our email hosting servers IP address is blacklisted.
We help the email hosting customers to identify the root cause if their outgoing email server’s IP address is blacklisted. We will contact the various DNSBL agencies to request removal and mitigate the impact on emails returned to the senders due to the blacklists.
If you are an email hosting customer and your email server’s IP address is blacklisted, we will replace your email server outgoing IP address with our IP reputation protection that usually takes less than an hour to restore your outgoing emails.
