I went back and searched my email. It was an RSA-2048 S/MIME certificate issued by Aldi Süd and Apple Mail now warns that the certificate is expired (the email was from a few years ago, when the certificate was valid). The email came from a supply chain person in their Hong Kong office - maybe that explains the level of security?
