I've been getting various DMARC "failure" reports from some recipients' email servers (see example below). I thought this kind of problem had been solved a while ago, given DMARC having become fairly widespread.
Is this due to a few lame email servers not properly implementing DMARC checking, or does the ESR list forwarding mechanism need improvement? P.S. What follows is the text part of the email, I can supply the (almost endless) headers if that would be helpful. ---- From: [email protected] To: [email protected] Date: Thu, 11 Jul 2019 21:06:43 -0400 (EDT) Subject: DMARC Failure Report for iment.com ([email protected], ip=63.245.210.104) This is an email abuse report for an email message received from IP 63.245.210.104 on Thu, 11 Jul 2019 22:06:41 -0300. The message below did not meet the sending domain's DMARC policy. For more information about this format please see http://tools.ietf.org/html/rfc6591 .
