Using the Sendmail Reject List to manage spam

The Sendmail Reject List is a list of email sources that you identify as sources of unsolicited email. The mail server rejects email messages from these sources thus prohibiting further relay to any site hosted on the server. For example, if you include the IP address 1.2.3.4 in the Reject List, all email messages that originate from this address will be blocked from being relayed to any site hosted on the server.

The email source can be:

- An email address - The email address is blocked.

- A site - All email addresses that originate from the site are blocked.

- An IP address - All email addresses that originate from the specified IP address are blocked.

If you enter a partial IP address, email messages that originate from any IP address in the subnet are blocked. For example, specifying 1.2.3 will block all IP addresses in the subnet, 1.2.3.0 through 1.2.3.255.

You can also use the Spam Filter service to enable user-level control and management of spam. The Sendmail Reject List and spam filter service vary in their approach and flexibility in managing spam.

- Note: The Spam Filter service offered in the earlier versions of Ensim Pro/Basic is now renamed to Sendmail Reject List. Ensim Pro/Basic introduces a new Spam Filter service that uses the SpamAssassin™ tool to enable spam scanning.
