Once you've added your S/MIME certicificate in the app's Settings, you're ready to send and receive messages!

Sending encrypted e-mail

  • After choosing your recipient, you will be notified whether they possess a certificate or not.
    • Certified users are displayed in Green
    • Users without a certificate are shown in Red
  • If your recipient does not hold a certificate, the app will notify you when pressing the send button since the recipient may not be able to correctly view your e-mail

Receiving encrypted e-mail

  • Signed e-mails will display an orange ribbon icon next to the sender in your Message List and Message View
  • Encrypted e-mails will display a green padlock icon instead
  • Inside a message, tap View security info to see additional information about the sender's certificate
