AOL Mail updates DMARC policy to 'reject'

Today we moved to change our DMARC policy to p=reject. This helps to protect AOL Mail users' addresses from unauthorized use.

It also stops delivery on what previously would have been considered authorized mail sent on behalf of AOL Mail users via non-AOL servers. If you're a bulk sender on behalf of AOL addresses, that probably includes mail sent from you.

This can include but is not limited to:
  • Email service providers (ESP) sending mail on behalf of businesses using AOL addresses
  • Websites with "Share with a friend" functionality, sending mail using AOL addresses
  • Small businesses using other 3rd party services to send mail and communication between their employees and / or customers
  • Services used to forward mail
  • Mailing lists (listservs)
Mail sent on behalf of AOL Mail users to DMARC-compliant domains will be rejected by those domains unless the mail passes SPF and/or DKIM authentication checks AND the domain(s) used in those checks match aol.com.

We recognize that some legitimate senders will be challenged by this change and forced to update how they send mail and we sincerely regret the inconvenience to you.

What should you do?

In almost all cases, we recommend that you switch to sending mail from your own domain. You may also consider using AOL SMTP directly.

For mailing lists, also known as listservs, we recommend configuring reply behavior to fill the From line with the mailing list's address rather than the sender's and put the actual user / sender address into the Reply-To: line. Please also note that current "auto unsubscribe" logic based upon bounces might be too rigid until this change has been in place for a while.

For website operators with 'share from email' functionality, please consider using an email address from your own domain as the From address and populate the Reply-To: line with the address of the person sharing.

If you have specific questions around configuration and authentication options as well as DMARC related inquiries, please contact us at dmarc-help@teamaol.com.
