The mail app on Ventura 13.2.1 keeps warning me that I don't have encryption certificates for my message recipients. I am not trying to send encrypted e-mail - why does Mail keep warning me about something I'm not trying to do?
MacBook Pro 16″, macOS 13.2
The problem occurred when trying to send an unencrypted message. The solution was to turn off "Protect Mail Activity" in the Privacy tab in Settings. I found an article that reported that this setting interferes with Mail.app's usual interaction with S/MIME. I've not had a problem since turning this setting off.
Thanks for your help...

I was able to find a fix. Long story short, you must get an S/MIME certificate installed so that you can purposely turn on encryption by starting an e-mail to yourself and then turn it off. This link details how to get a free S/MIME certificate. https://peterstevenho.medium.com/6-steps-to-enable-apple-mail-encryption-8b2250f98361
If you want more details, let me know.
Hi HugginsDavid,
Does this happen when trying to send mail, receive mail or both? Are you able to access your mail from the web without an issue? We look forward to hearing back from you but in the meantime here's a resource that might help: If Mail on your Mac can’t verify a server’s certificate
Take care.
