Probably not a permission issue, as I think, the error message would
tell you.

The certificate is used on the server side, I suppose. So check the
path's for the cert.

exim -n -bP tls_{certificate,privatekey}

To be on the safe side: the the permission on the *whole* path (e.g.
using `namei -l …`), the cert and key file must be readable by the Exim
runtime user or group. If you use the cert as a client (during
transport), beware that normally Exim doesn't initialize the
supplementary groups, (see transport option `init_groups`).

Check if the cert's modulus matchs the key's modulus:

openssl x509 -in <certfile> -noout -modulus
openssl rsa -in <keyfile> -noout -modulus
