When a customer tries to send us an Email, and they are blocked, what happens to the Email sent?

Our first line of defense to combat spam is to block Email servers that have sent spam in the past. This method is called blacklisting. We use various blacklists, some external and some of our own custom lists.

Email originating from a blacklisted server is bounced back to the sender. The Email is not delivered to the recipient.

An Email similar to the one listed below will be received by the sender.

If this is an error, please create a new ticket. Please include the IP address of the blocked Email server. We will whitelist the server to permit Email to enter our network.
