Looking to start sending DMARC feedback, as dmarc is integrated with ISPC I'm not sure how to go about doing this as I'm concerned installing opendmarc may mess with the ISPConfig DMARC set-up. Any advice welcome, thanks!
OpenDMARC will not break your setup. http://blog.schaal-24.de/mail/dmarc-check-unter-debian-wheezy/?lang=en http://blog.schaal-24.de/mail/dmarc-reports-erstellen/?lang=en
