As far as I can tell Spamhaus has a de-facto monopoly on email blocklists. So maybe others don't have the Tor exits in their lists because they don't matter? > Does this > have an effect on Tor users? Yes. This means you cannot host a mail server and make it deliver email over Tor, similar how you cannot host a mail server at home, because all the end-user IP addresses are listed by Spamhau as well. (This is different from having your mail client (e.g. Thunderbird) connect to your mail server over Tor, these connections usually are _not_ blocked.) > How is Spamhaus actually used?

No. web/HTTP(S) traffic is filtered by other companies. Most notoriously Cloudflare. But there are others as well. What makes them worse, is, that they usually don't just provide blocklists, but do man-in-the-middle the whole HTTP(S) traffic.
