Hi list, I'm using opendkim milter with opendmarc milter. I noticed a
lot of messages from amazonses are getting refused by the dmarc milter.
After further investigation I noticed the if a message has multiple dkim
signatures only the first domain is reported in the Authentication
results header:
Feedback-Type: auth-failure
Version: 1
User-Agent: OpenDMARC-Filter/1.3.0

From: "Amazon.it"<promotion-it_at_amazon.it>
OpenDMARC refuses the message because only amazonses.com is reported in
the Authentication-results header, while the message is from _at_amazon.it.
Am I missing something here? Is this supposed to be correct?
Ty
