dmarc report faild ?
In the same vein, I am receiving forensic DMARC reports from mx01.nausch.org. Whenever I send a message to the mailing list or when my server sends a DMARC report, I'm getting a DMARC Forensic report. It's odd, because the actual report tells me both DKIM and SPF (in the the of a DMARC report) pass... Here is what I am getting : This is an authentication failure report for an email

[fdo] PSA: Mailman changes, From addresses no longer accurate
Hi all, We have hit another step change in aggressive anti-spam techniques from major mail providers. Over the past few days, we saw a huge spike in the number of mails we were failing to deliver to GMail and outlook.com in particular. It looks like it is now no longer acceptable for us to break DMARC/DKIM/SPF. These are DNS-based extensions to SMTP, which allow domains to publish policies as to

OT: DMARC / DKIM Failure Reports
Hi guys, when I send e-mails to CentOS mailing list <centos at centos.org>, I received DMARC / DKIM failure reports. Is it possible to solve this problem and if so how? This is the first report: This is an email abuse report for an email message received from IP 208.100.23.70 on Tue, 17 Sep 2019 15:56:25 +0200. The message below did not meet the sending domain's DMARC policy. For

[fdo] PSA: Google dropping a lot of list email
Hi all, There's a good chance that the people who most need to see this won't see it, but here goes anyway. Google is currently dropping a _lot_ of the mail we attempt to deliver to lists.fd.o subscribers. The immediate cause is sending on mail from domains with SPF/DKIM/DMARC policies which explicitly specify that lists.fd.o cannot relay mail on their behalf. Every time we do that, not

Sieve "foreverypart" and "mime" extensions (RFC 5703) now implemented
Hi, I have finally managed to implement the Sieve "foreverypart" and "mime" extensions (RFC 5703). These are now included in the main Mercurial repository and will be included in the next release. I will be fixing a few minor details in the coming week; e.g., interaction with "include" and "editheader" extensions needs more work. Still, in the mean time,

Mail server troubles
Hi, This is probably a bit OT, but here goes. I've been running our local school's mail server since 2013, with mail addresses for school staff and some teachers. The server is running CentOS 7 with Postfix and Dovecot, and it's a nice no-bullshit configuration with SPF, DKIM and DMARC. The school sends quite a lot of email out to parents, and sometimes, mail gets rejected:

[LLVMdev] Mails from IITH marked as spam
Dear Admin, It seems that mails from our iit.ac.in domain are being marked as spam. It would be nice if something could be done about this.
