self-signed root certificate

For some reason within the past 10 days the email address I use most frequently goes out with a "self-signed root certificate." Now many of my emails are encrypted rather than coming through as regular text. Apple support has helped me identify how not to use the digital certificate. However, I would like to remove it. None of my other accounts has such a signature. There is also a "private key" as a subset of the digital self-signed root certificate. How do I remove the digital certificate? Can I simply delete it, or will this cause problems?

I would appreciate consult on this issue. Thank you.

MacBook Pro 13″, macOS 10.13

The most expedient way to fix that problem is to remove the problematic Mail Account, and then add it again.

First remove: Remove email accounts in Mail on Mac - Apple Support

Then add: Add email accounts in Mail on Mac - Apple Support

Adding the account should provide updated certificates. I would have expected Apple to suggest that before delving into digital certificates though.

The "choose a product" list populates from the list of products Apple thinks you own. You can update that information here: Check your Apple ID device list to see where you're signed in - Apple Support.

I think your original idea is the way to go. Among Apple's suggestions, did they discuss removing that certificate using Keychain Access?

I can't imagine removing it will cause any more trouble than you already have, but be sure to create a backup first: Back up your files with Time Machine on Mac - Apple Support. That just goes without saying.

John, thank you for your reply and this suggestion. One Apple advisor suggested this. I did remove the email account with which I am having difficulty in Mail on Mac and added it again. However, the problem persists. I am puzzled.
