MandarisI use Fastmail for my mail service and it was nice that it was mentioned in this article. I'm going to have to add reviewing my post about BIMI to my list of things to do.
Email authentication is evolving, and Ed25519 DKIM keys promise clear advantages over traditional RSA: smaller keys, faster verification, and stronger cryptographic guarantees. But those benefits only matter if mailbox providers actually support the standard. To find out, Red Sift analyzed DKIM behavior across major email platforms to answer critical questions for email administrators: can Ed25519 keys be deployed safely today without risking authentication failures?
Unfortunately, I’m still at a place where I can justify registering a trademark so that people can see my picture in their email.
