I'm seeing the reported DMARC error message for all of the following e-mail domains. Hotmail.com Yahoo.com Comcast.net MSN.com As well as on individualized domain names that are apparently hosted on one of the above. This appears to be a problem of a magnitude that perhaps only the application developer (ListServ/Peach Ease) can fix? At the moment I can only think of 2 solutions for managing this at the individual ListServ level: 1. Encourage users to change their e-mail accounts to a different provider. 2. Temporarily turn off automatically deleting accounts that "error out" until the issue is resolved. If anyone has other strategies, please share!

It is likely that these from recipients who use same-envelope forwarders to Yahoo, Hotmail and Comcast and I have an SPF record that prohibits that. All of these are from a new anti-forgery tool called DMARC - see http://dmarc.org.
