@Jerry@hear-me.social would adding those txt records cause any issue to a wildcard redirect I use for myself?
I have xxxxx.com and an auto redirect by my dns provider so that anything sent to name@xxxxx.com is forwarded to name@gmail.com so when I give out the address I can see if it's been shared.
I like the idea of protecting against unauthorized use but wouldn't want to lose my throwaway capability.
I find email servers to be akin to dark arts so am at a loss here tbh.

@b3lt3r@mastodon.b3lt3r.com I'm far from an expert, but if your redirect is at the server, and your server adds a ".forward" to the email, and does not alter anything, you should be fine because your SPF and DKIM should pass. If your redirect is via an email client, or the server doesn't add a .forward, it may alter the email slightly, but in a way sufficient for DKIM to fail because the hash won't match any longer. But, I think in this case, if SPF passes, your email client would still accept it since the original DKIM passed before the forwarding. It gets really complicated. Suggest you try it. And this is based on my understanding, which, who knows?
