After upgrading to 2.31 I'm getting this
  error. Not sure what I'm doing wrong.

  

  No (No signatures could be verified because the chain contains
  only one certificate and it is not self signed.)





ssl = yes



ssl_cert = </etc/exim/certs/ctyme.com.crt

ssl_key = </etc/exim/certs/ctyme.com.key

ssl_ca = </etc/exim/certs/ca.crt
