Dear Mailman-Users,
I have a Mailman instance running on a vServer with Plesk, but am using
email services from my provider (different IP and MX-Domain than the
Mailman machine). Emails in the format n...@domain.tld generally seem
to work. However, when I send an email from the same adress to one of
my Mailman lists at subdomain.domain.tld, I get many bouncees who will
eventually be removed from the list.
My question is: What is wrong here, my SPF or DKIM settings OR my
Mailman-DMARC settings?
My Mailman-DMARC settings are the following:
from_is_list: No
anonymous_list: No
dmarc_moderation_action: Munge from
dmarc_quarantine_moderation_action: Yes
dmarc_none_moderation_action: No
From Google I received reports of which the following XML is a
clipping:
<?xml version="1.0" encoding="UTF-8" ?>
<feedback>
<report_metadata>
<org_name>google.com</org_name>
<email>noreply-dmarc-supp...@google.com</email>
