Or maybe we can simplify mail systems more. If mail, a system used to send messages across computers cannot work on "residential" IPs, then we can make it work on "residential" network since most nodes are "residential". You can look at.
humaaraartha.in. TXT And you'll find spf records there. Maybe it's just time to say, reduce the requirements of mail hosting to just static ip and DNS in a world where most don't even have a static ip! Thanking you Sagar Acharya https://humaaraartha.in P.S. I see that you're talking substance and truth to some extent but discarding residential IPs and this need for reverse dns is outrageous! What is the point of reverse DNS in today's world? 7 Sept 2023, 14:25 by [email protected]: > Learn the basics.
