Process model created by Basic User does not send email

On a cloud installation, process models created by a Basic User are not sending email.
The problem is limited to Send E-Mail nodes, task notifications work.

Send E-Mail nodes are configured as follows:
From: Process Model
Run as whoever started the process

Even when run by a System Administrator, the nodes still do not send email.

If the process model is created by a System Administrator, it will send email, regardless of who started it.

I could not find documentation on what seems to be a weird permission problem. The Basic User I am testing with is in the following groups:

  • Application Users
  • Database Administrators
  • Designers
  • Process Model Creators
  • Tempo Users
  • The custom groups defined as Viewer and Administrator for the specific process model (and relative folder)
