Hello Community,

While trying out Broadcast feature - I ran into following error:- Please refer to the attachment:

  1. S/MIME identity without logical name "DONOTREPLY@TPCUS.COM" does not exist.
  2. Signing Error: S/MIME without logical name "DONOTREPLY@TPCUS.COM" does not exist.
  3. Signing mail failed - no valid certification for sender address?

Please guide how to resolve the same.

Hi Kumar,

It sounds like the easiest solution could be disabling S/MIME.

You can do it from Administrator -> Quick Tasks (all the way to the right) -> Configure S/MIME.

From there go to the 3rd tab, "Activate S/MIME", and uncheck everything.

Then try again sending the email.

Kind regards,
