Greetings, I'm attempting to send email to m...@openbsd.org, and getting a lot of DMARC failure reports. SPF, DKIM, and DMARC work fine for me when I am not using a mailing list. My SPF TXT record is
"v=spf1 a mx ip4:198.251.82.194 -all" and my DMARC record is "v=DMARC1;p=none;pct=0;fo=1;rua=mailto:postmas...@ircnow.org;ruf=mailto:postmas...@ircnow.org"; However, I sent two emails in the last 10 days, and received 20 failed DMARC reports. I am not sure if these two emails were received: https://marc.info/?l=openbsd-misc&m=170354063924689&w=2 https://marc.info/?l=openbsd-misc&m=170274207904871&w=2 As of today, I adjusted the DMARC record from p=quarantine to p=none, with hopes that fewer emails would get rejected. I'm not sure if 1) these failed DMARC reports are normal for mailing lists, and 2) if there's anything else I can do to reduce the failure rate. Below is a sample fastmail DMARC report: <?xml version="1.0"?> <feedback> <version>1.0</version> <report_metadata> <org_name>Fastmail Pty Ltd</org_name> <email>repo...@fastmaildmarc.com</email>
