DMARC errors when sending email to comcast.net addresses was created by robertadmiller
We are getting the message copied below the "***" line in this email for the comcast.net email address of a member. Is there anything that we can do about this on the FreeToastHost side, or anything that the support and development team can do?

I saw a post about a different message last year related to outgoing emails from FreeToastHost. It received the reply, "it is because of the new DKIM and Dmarc rules. email that is forwarded sometimes breaks, depending on the receiving email service", but the reply didn't include any suggestions for resolving the problem.

Thanks in advance for any information you can share.
