Mark, Good straw to grasp at. I thought SElinux had already been disabled but it hadn't. It seems to be working now.
Do we have better advice than just "disable SELinux" to offer?
I ask because "solving" the DMARC "problem" seems to involve trust of Mediators (the technical RFC term for middlemen like Mailman) by Author Domains (RFC-ese for domains with DMARC policies about verifying From:). Asking upstream to trust sites which have deliberately disabled security features seems like poor strategy at best.
