Thanks Stephen. I think it would kind of be a dealbreaker if some folks couldn't get mail with no way to remedy.
Are there other hosts? How is this not a bigger issue for Mailman users? Maybe most are big institutions that have their own SMTP relays and dedicated staff to keep deliverability/reputation high? Or maybe a lot of people are using DMARC mitigation so that the 'from' address is always the list address? I am curious how well that works. I'll start a separate thread on that.
