Now I've put it back to "no", as there are other settings that were backported to the .el7 mailman version (so from upstream 2.1.18 to mailman-2.1.15-26.el7_4.1.x86_64) and from today, here are the settings that were adapted : dmarc_moderation_action "munge from" dmarc_quarantine_moderation_action : "yes" So that means that for people without any DMARC policy set to either p=quarantine or p=reject , nothing will be changed in the headers, so as before And for for impacted originator domains with such DMARC policy, the "from" will be adapted, so still let the mail being processed and delivered, but without a risk of being rejected/bounced by mail servers implementing such DMARC checks Let's see how that goes during the day -- Fabian Arrotin The CentOS Project | https://www.centos.org gpg key: 56BEC54E | twitter: @arrfab -------------- next part -------------- A non-text attachment was scrubbed...
