Feedback Loop Technical Requirements

Requesting a Feedback Loop:

When requesting a feedback loop, your domain must comply with AOL's reverse DNS guidelines. Additionally, your request must comply with one of our measures of IP ownership.

IP Ownership:

The FBL process must be able to establish that the FBL applicant has a right to receive abuse complaints for the IP(s) in the submitted request. To establish IP ownership, one of the following five criteria must be met. Please note that if you use a subdomain in your FBL email address, that subdomain must be shared to satisfy the selected requirement below.

  • The reverse DNS for each IP shares the FBL domain (including the subdomain, if used).

    A valid example would be:
    FBL email address is: aolfbl@accounting.aol.com
    192.168.1.1 resolves to mailserver1.accounting.aol.com
    192.168.1.2 resolves to mailserver2.accounting.aol.com

  • The domain WHOIS for each IP's RDNS contains the FBL email domain (including the subdomain, if used). The domain may appear in any of the listed email addresses.

  • At least one authoritative nameserver for each IP shares the FBL email domain (including the subdomain, if used).

    A valid example would be:
    FBL email address is: aolfbl@accounting.aol.com
    192.168.1.1 authoritative nameserver is ns1.accounting.aol.com
    192.168.1.2 authoritative nameserver is ns1.accounting.aol.com

  • The IP WHOIS information for each IP contains the FBL email domain (including the subdomain, if used). The domain may appear in any of the listed email addresses.

    A valid example would be:
    FBL email address is: aolfbl@abuse.aol.com
    192.168.1.1 and 192.168.1.2 IP WHOIS contains the line: OrgAbuseEmail: abuse@abuse.aol.com

  • The ASN WHOIS information for each IP contains the FBL email domain (including the subdomain, if used). The domain may appear in any of the listed email addresses.

    A valid example would be:
    FBL email address is: aolfbl@abuse.aol.com
    192.168.1.1 and 192.168.1.2 ASN WHOIS contains the line: OrgAbuseEmail: abuse@abuse.aol.com
