For a browser game, password reminder/recovery option. The emails are sometimes/frequently not delivered due to my poor setup :) So, I started to learn abut all the SPF, DKIM and other monsters and try to grasp how it all works :)

How to setup "SPF"?

Let's say you have a domain of you server (server.com) that runs the script and another domain for your game (game.com).

I understand you first need to create an email (something@game.com), then you need to add "SPF MX record" to the server.com DNS?

Like this: TXT = "v=spf1 mx include:game.com -all"? Or the orther way add TXT = "v=spf1 mx include:server.com -all" to the game.com DNS?

I'm not sure I grasped how it works :D
