It looks like there are quite a few Synchting relay servers on networks which are listed on the Spamhaus DROP list. Even if traffic is end-to-end encrypted, this sounds a bit ugly to me.

Today I learned that #SpamHaus doesn't work with IPv6: I get an "open resolver" error even though I haven't exposed my DNS server to the outside world—just by using IPv6—because SpamHaus is worried that users might bypass rate limiting by constantly changing their IP addresses, so it blocks ISPs that assign /64 or /56 blocks to their customers...

So on one hand, we have IPv6, which is there to provide plenty of IP addresses, and on the other, a service that refuses IPv6 because of it 🤦‍♂️

#Spamhaus doing that thing where I log in and it says “welcome back” but without my name or submission history. Then tells me I need to log-in. Which I already did. And it shows a log-in button. And since it won’t accept I’m already logged in I can’t even log out and try to log in again.

I bought a domain on Porkbun, use Linode as the DNS and Purelymail for mail.

Spamhaus has my domain blocked, and I have no idea how to get off the list. I tried reducing whois privacy on Porkbun. I contacted Spamhaus them twice.

Spamhaus won't give a reason, but mxtoolbox states Spamhaus says " Reason for listing - We were unable to find an IP Address for THE-DOMAIN." But what does that even mean? DNS A record? To where? Purelymail?

Any tips on how to get the domain unlisted?
