After you download your Certificate from your PC, you may export it and send it to your email along with the Intermediate and Root Certificate.

Now install the Intermediate Certificate using the same process.

Now, install your PersonalSign Certificate. It will ask for your private key password (this is the password that was auto-generated when you downloaded the Certificate.)

Now go to Settings >Profiles.
Under Profiles, you will find three profiles.

Now go to your account and passwords.

Select the email account for which you are installing the Certificate.

Go to Advance. Then, scroll down to S/MIME and enable it.

After that, make sure you close all.
