similar to: [fdo] PSA: Mailman changes, From addresses no longer accurate

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

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

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

I have no problems with Gmail from Digital Ocean. But I have both spf, DKIM, DMARC and a reverse pointer. You need to not look spammy. One advantage to using a VPS is your IP is unique. That is you don't share it with a spammer. Not so with hosted services. ? Original Message ? From: M.Roos at f1-outsourcing.eu Sent: October 26, 2020 1:06 AM To: dovecot at dovecot.org; sebastian at

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:

I have a goal of securing email. Updated the company mail server and DNS (CentOS 7 + Postfix, otherwise pretty stock) with support for SPF, DKIM, and DMARC. So far, all good, and everything "just works". Our mail server has supported SMTP / TLS for a long time, but recently I've been considering requring TLS all the time. Is there anybody here who's done this? Has it

I know it is not dovecot who should fix this. But anyone using dovecot is using an MTA, and receiving spam ;) I know how to look at email headers. Spf and dkim is not solving anything here. -----Original Message----- From: Sebastian Nielsen [mailto:sebastian at sebbe.eu] Sent: donderdag 11 juni 2020 10:23 To: Marc Roos; 'dovecot'; 'users' Subject: SV: handling spam from
