I’ve decided to go full-in with my own mail server. The #ProtonMail bridge over SSH+VPN tunnel is no substitute for a proper mail server - plus it’s awfully slow when used as a full IMAP server and it breaks the IMAP implementation in a lot of ways.
I’ve created my new domain, gone through the configuration of DKIM/DMARC/SPF like a good postmaster, just to get immediately blacklisted by @spamhaus on my first outbound email.
I’ve been through this before, but in my previous experiences a blacklist removal ticket would be either resolved automatically or within a couple of hours at most.
In this case, nearly 24h and three tickets later and nothing is moving. Not even some directions on how to get removed or an ETA. The mailboxes have already been all migrated with forwarding configured on the old addresses, but outbound email is still broken because being blacklisted by a single company means being unable to communicate with nearly any mail servers out there.
Does anyone have any tips on how a #Spamhaus blacklist removal process can be sped up?

There's an older article that's gone now (you can sometimes find it in an archive) titled "The hostile e-mail landscape"
After a few years with my e-mail on Hetzer, most of it seems to get through now. mail-tester.com is a pretty decent checking tool.

I am 3 years into my "own email server" and it has been (and still is) painful. Reverse DNS was one of the thing I remember was hugely important to resolve exactly. Also, remember that you might have IPv6 being used, so don't forget that arm of erverything.
And finally, there are some email systems out there that will never communicate with you, most notably some Outlook servers, for instance Teams invites never reaches me (a good thing, though).
