Standard Reputation Services Database

The Standard Reputation Services includes a database with the following lists:

  • The Known Spam Source List is a list of IP addresses of mail servers that are known to be sources of spam.

  • The Dial-up User List (DUL) is a list of dynamically assigned IP addresses, or those with an Acceptable Use Policy (AUP) that prohibits public mail servers. Most entries are maintained in cooperation with the ISP owning the network space. IP addresses in this list should not be sending email directly but should be using the mail servers of their ISP.

  • The Emerging Threat List (ETL) includes IP addresses of mail servers involved in active ransomware, malware, or other email threat campaigns.

For the Standard section:

  • You can enable or disable the lookup of selected lists by using the check boxes.

    • Select the check box to enable the list.

    • Clear the check box to turn off the list. The Email Reputation Services system will skip that list during a lookup request.
