Plesk Onyx for Linux

Symptoms

Mail messages from Amazon or other particular senders do not pass the DMARC filter and placed directly into Spam, or rejected by dmarc handler, as can be observed in /var/log/maillog:

CONFIG_TEXT: spamd[11617]: prefork: child states: II
dmarc[15077]: Starting the dmarc filter...
dmarc[15077]: DMARC: REJECT message for user@example.com
postfix-local[15071]: message discarded by a mail handler
A record like the following can be found in /var/log/maillog:
CONFIG_TEXT: dmarc[15077]: Wrong the essential DMARC policy parameters for user@example.com
Correct SPF and DKIM are present in the message, as can be observed in /var/log/maillog:

CONFIG_TEXT: spf[15067]: Starting the spf filter...
spf[15067]: SPF result: pass
spf[15067]: SPF status: PASS
dk_check[15076]: Starting the dk_check filter...
dk_check[15076]: DKIM verify result: DKIM verification (d=example.com, 1024-bit key) succeeded
The following can be found in /var/log/maillog through records of email handling:

CONFIG_TEXT: server01 dmarc[27080]: DMARC: message moved to QUARANTINE for john.doe@example.com

From: John Doe newsletter@example.org
Domain in the From: header has "relaxed" SPF and DKIM policy (adkim and aspf are absent, or equal to r):

# host -t txt _dmarc.example.org

What would I do for the combination Plesk Onyx 17.8 on Ubuntu 14.04? T/T

@Tom Tonic The hotfix does not depend on the version, so it should not break the Plesk. However, if you facing the same issue on Plesk Onyx 17.8 on Ubuntu 14.04, I would like to recommend you to create a support request to look closer.

Hi, what would I do for the combination Plesk Onyx 17.8.11 on Debian 8.11?

Mail messages from Mailchimp do not pass the DMARC filter and rejected by dmarc handler. As can be observed in /var/log/maillog:

Nov 23 17:49:57 server dk_check[35313]: Starting the dk_check filter...

@Salecroix Charly

First of all, we need to understand is it the same issue or another one, as the bug was fixed in 17.5. So I would like to recommend you referring the troubleshooting steps from

https://dmarcian.com/start-dmarc/ and https://dmarc.org/wiki/FAQ to get some additional details. If it will not help to shed light on the issue, you you may submit a request to support: How to submit a request to Plesk support?

@Robert Asilbekov

Hi Robert Asilbekov,

Indeed, is it the same issue as the bug was fixed in 17.5.
I followed the problem solving procedure for "Plesk Onyx 17.8 on CentOS 7", CentOS getting closer to Debian.
So I can tell you that by following this procedure the problem is now solved and Mailchimp's mail messages now pass the DMARC filter.

I invite you to test the resolution of the problem by yourself and to provide to all users experiencing this problem in Debian this solution.

Have a niceday everybody.
