So if someone send a email with a bad signature to an IETF list from a domain that has a reject policy, and the IETF server forwards it to my email email provider, my email provider rejects it. Now the IETF email server counts that as a bounce. Too many bounces in a row and the IETF server unsubscribes me from the list. This does not seem OK that anyone can trivially send some SPAM and get me unsubscribed. What's the right advice on how the IETF server should be run? Now to a more detailed problem - Jana sends lots of email to the quic list. I don't get any of them. It appears that my email server (run by rackspace) rejects them with an Diagnostic-Code: smtp; 550 5.7.1 Email rejected per DMARC policy for google.com (G15) If Jana sends the email directly to me, it works. This seems to point at the IETF server is doing something that breaks signature in Jana email. I realize this is not the "debug your email" list, but I have no idea where is the right place to ask about this so I sent it here. Sorry. Can anyone tell me how their DMARC system views the emails from Jana to the quic@xxxxxxxx list ?
