If they use forwarders, SPF will fail in the case the envelope sender
isn't rewritten. Check your logs for that.
false, every forwarder changes envelope sender, so if spf should keep
pass, its the new forwarding host job to ensure this new envelope sender
have spf working
problem is that it breaks dmarc aligment, but non aligned mails is still
fine for maillists
hopefully mailman will ARC-Sign / ARC-seal before it breaks dkim
let the experts do there work
