"Unable to verify message signature" now shows up on all my emails from @me.com, help?

First this morning there was a privateKey request that popped up every time I tried to send an email from this account. emails would not send unless it was dealt with. I finally submitted, added my PW then clicked "always allow" on the privateKey request. Now the emails can send, but the arrive on the receiving end with this alarming note "Unable to verify message signature" (tested by sending from the @me account to another email account of mine). What is wrong, how bad is it, and how do I fix it? Thank you!

MacBook Pro 15″, macOS 12.2

Welcome, JosiahHawaii!

Thanks for using Apple Support Communities! If we understand correctly, you see an error about an email signature when you attempt to send an email from your email account. It also sounds like if this message is bypassed, others get a message on their end about your email signature. We're glad you reached out. We'll do all we can to help get you pointed in the right direction.

First, check out this link to learn more about what to do If Mail on your Mac can’t verify a signed email. As it shows there, you'll want to verify the trusted certificates on your Mac. Here's more information: Trust a certificate on Mac.

If you have followed all the steps on that page and still need assistance, you'll want to contact Apple's Mail Support directly.

All the best.
