Description

Steps to reproduce

So I do get S/MIME mails regularly, but I did not install the S/MIME certificate for mail (I don't need it to decrypt it in Nextcloud Mail). Still the nextcloud.log is full of

Failed to find a suitable S/MIME certificate for decryption

I can see it makes sense, since it's an error, but I can also see that it should not be a fatal error. Just wanting to put it here, feel free to close if you think error level is correct.
