@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?

@Jerry@hear-me.social ok - I'll try it on a less critical domain first, thank you. I run most of my own services from here to avoid any cloud usage but the one thing I do not dare to host is email - I can't see any refinement in configuration/management has happened since the '70s :-)
