• test if cert is ok with

  /opt/zimbra/openssl/bin/openssl verify -CAfile commercial_ca.crt commercial.crt

  [root]# /opt/zimbra/openssl/bin/openssl verify -CAfile commercial_ca.crt commercial.crt
  commercial.crt: OK

If you use a wildcard certificate (e.g. *.schnuerle.com) for your internet domain - so edit your local hosts to get the local ip if you use this internet domain in your local network:

10.10.10.21    mail.schnuerle.com
