Hello, we have a problem with email sending. During the installation of nintex we unchecked "Use Exchange for mail integration" and setup smtp connection.

But despite this we have a problem with email sending.

Text of an error: "There is no connection string for the  destination email address system@k2.local."

It's logically, just because we have only strings with our smtp settings. Also Connection String Editor has smtp settings (see attachments).

Nintex version: 13.03.2023 K2 Five (5.6) (5.0007.1000.1).
