How can I remove an Adobe Reader created digital ID from Apple Mail?
Mac mini late 2014, 3 GHz dual-core I7, Big Sur 11.7.10
I made a simple digital signature in Adobe Acrobat Reader 2023.008.20470, which it stored in Mac Keychain Store, for signing a state government PDF document, which I attached to an email. When I sent the email, it demanded my password, twice, apparently to attach a digital ID signature.
Now it stops emails that I send from that account without any intended signature like this:
It's an unnecessary pain. It won't send the email if I click "Deny". I've tried deleting the signature in Adobe Reader Preferences with "Remove ID"
and it doesn't work.
How do I get rid of it?
