If you get a DMARC failure for a mail with a NULL sender, than you a) don't sign your outgoing bounces/OOO with DKIM b) you don't have SPF records for your sending mail hosts (e.g. smtp11.infineon.com) > How to overcome such issue as a sender? Add SPF records for every server that is sending mail out to the internet and/or sign bounces/OOO with DKIM.
