[exim] Verify fingerprint of TLS certificate

Hi

I'm looking for a way to verify the fingerprint
of a remote server's certificate when sending
mail.

I understand tls_verify_certificates can be used
to match the certificate. Is there a way to verify
the fingerprint instead?

What I'm looking for is what can be done in postfix
with a tls_policy_map like this:

domain.tld fingerprint match=xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx

Thanks
David
