You are mistaking the point of tls_verify_certificates. If a *client*
connecting to exim presents a certificate, exim will verificate this
one against the list of trusted ones in tls_verify_certificates.

OTOH if the client (Mail.app) wants to verify the cert exim is
presenting to it, the client will need to have access to the ca-cert
used to sign exim's cert.

BTW is your server accessible from the internet? We could try and check
whether we could verify the cert if it was.
