Update 09:23: The issue has been resolved and sending emails is possible again.

The TurboSMTP email service is temporarily unavailable. This affects the entire Public Cloud and all Private Clouds that do not have their own integrated SMTP server. The affected features include the use of the sendEmail() function and the sending of invitations, password reset messages, and account verification emails. We apologize for this inconvenience and are already working to restore service.
