This worked well for years until we moved to a new mail spam and security service and introduced stricter DMARC and DKIM settings for all our mail. This is what broke one of our larger lists (our alumni outreach list, and of course it’s Homecoming next week, and the last email resulted in 650+ bounces for DMARC failures..mostly from aol and yahoo. ) Is it possible to have the email addresses of the mailman administrivia addresses (-owner -bounces, etc) be the FQDN, but outgoing list traffic be set to just the domain?
