[arin-announce] Community Consultation on DMARC for ARIN Mailing Lists

Tue Aug 22 09:56:56 EDT 2017
ARIN received a suggestion via the ARIN Consultation and Suggestion
Process (ACSP) to add DMARC (Domain-based Message Authentication,
Reporting, and Conformance) support to ARIN mailing lists. In our
response to the suggestion we indicated a community consultation would
be conducted by Q3 of 2017 to support our research into a possible ARIN
A description of DMARC is currently available inside Informational RFC
Additional draft documents are also being worked on inside the DMARC
Working Group of the IETF:
The author of ACSP 2017.11 also provided reference to a Mailman support
page for DMARC (note that ARIN currently uses Mailman 2):
In our initial response to ACSP 2017.11, we indicated it was not at the
time clear if it was possible to operate a mailing list in a manner
which both meets existing community expectations for mailing list
behavior and conforms to DMARC's expectations regarding header/sender
alignment. We offer the following questions to solicit your input on
this topic. Provided there is support to move forward with a DMARC
implementation, your feedback will be used to help inform the
development of a plan that accommodates DMARC and prevents potential
negative impacts to participants on ARIN mailing lists.
1. Should ARIN implement DMARC for ARIN mailing lists?
2. Do you have guidance you would like ARIN to consider when
implementing DMARC for ARIN mailing lists?
Your answers to these questions, including any additional information
you would like to provide, will help guide our next steps in response to
ACSP 2017.11. Thank you for your participation in the ARIN Consultation
and Suggestion Process. This consultation will remain open until Friday,
15 September 2017.
