It isn't even necessarily 'residential' IP's. It's IP's that don't have a valid reverse dns, preferably one that is also forward resolvable. Most ISP's won't let you set your reverse DNS on 'residential' connections, so it ends up being a blocker. Now you could set up a vpn tunnel to a vps provider that lets you set your reverse dns, and then things get a bit easier.
So prereqs -
1) Valid reverse DNS on your sending IP. Preferably with a hostname that is also forward resolvable.
2) SPF Records
3) DKIM
- 7kay 6y agoYou're right, that's the basic ingredient #1 I forgot to mention. Functional rDNS is essential. You don't want to have your mail server running at home anyhow. A friend of mine had a janky setup at home until I convinced him it's a bad idea.
- krageon 6y ago> You don't want to have your mail server running at home anyhow I do in fact want this. It may not be possible, but I definitely want it to be.
- piaste 6y agoAnecdotally, I have a valid reverse DNS on my home ISP-provided static IP, and when I tried setting up a mail server I got blacklisted on the spot. (I eventually went with a Tutanota account, fwiw)
