> there's a lot of pressure toward using the big providers, and that's dangerous This is true and you mention this in other posts. The resounding answer to "how do I run my own mail server" is "don't" and that creates a dangerous environment where we abandon a previously working and useful decentralized part of the core internet because corporations do not accept our individual participation. This is a form of censorship and I really don't know the best way to approach it. If a message is signed with DKIM there is a statistically insignificant probability that it is not from the asserted sender. Every MX should block based on content and behavior after initially accepting based on sender validation (SPF/DKIM). It seems like we need an email advocacy group to fight the long fight and tighten the screws on individual companies with overly protective policies like comcast and att. Perhaps even working at a federal/eu policy level would make sense.
