I noticed I was having issues with mail from mailing lists when I specified a DMARC reject policy for my domain, so I ended up changing it to unspecified for the time being to allow the receiver to decide how to deal with a DMARC failure. Not ideal, but DMARC (and DKIM signing for that matter) and mailing lists don't play nice together.
