Bad certificate format -9,808

I’ve been having this problem since the 18.3.1 upgrade. Is there a solution? My emails are not being sent and i don’t know why. I get the message that says “bad certificate format -9,808.” Is this on my phone/computer? Or is this a problem with my email provider? There phone gives me the 9808 warning, but my Mail likewise does not recognize my emails.

iPhone 15 Pro Max, iOS 18

It is an issue with the iOS. Encryption is not working properly, and the process has become corrupt. So, what you need to do is...
