Subject: Set headers in DMARC reports to prevent out-of-office replies
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=ea60313bde548e91d5718b7b35f98821688929b4;p=thirdparty%2Frspamd.git

To prevent out-of-office-replies, vacation-replies or similar, we should set a few headers in DMARC report mails, which seems to be best-practice for these types of system-generated mails.
