MeSign Root Certificate
The MeSign root certificates are built into MeSign APP and trusted, you don't need to do anything. The
following information is for your reference and understanding only. However, if you need to use or trust
MeSign issued email certificates in other email client software, you need to install the following root
CA certificates and related intermediate root certificates in these software.
