The receiving server could require proof-of-work for the first message from a sender to a given receiver,
at this point mailing lists are dead

It could be introduced gradually: if a proof-of-work is provided, then the message is allowed to skip the spam filter.
Yes, because that totally will not harm the small senders (often individuals) whose newsletters can easily reach thousands / tens of thousands.

all mailing lists, yes. Look at open source mailing lists.
- timmaxw 6y agoSuppose you have a newsletter with 10,000 subscribers. You need to perform a proof-of-work the first time you send an email to each new subscriber; so, 10,000 proofs-of-work. Each proof-of-work costs $0.001. This adds up to a grand total of ten dollars. Or, to put it a different way: $0.001 is very roughly equivalent to a few minutes of CPU time. So if you have a single-core server dedicated to running your mailing list, you can onboard several hundred new subscribers every day. Remember, the sender only needs to pay the proof-of-work when someone first joins the mailing list and receives the initial message. So, I don't see how this will kill mailing lists at all.
