kolban-google opened a new issue #18077: URL: https://github.com/apache/airflow/issues/18077
### Apache Airflow version 2.1.2 ### Operating System Debian ### Versions of Apache Airflow Providers Google Composer ### Deployment Composer ### Deployment details _No response_ ### What happened I was trying to configure sending of alerts via SMTP. I must have made a configuration error and I get the error "Failed to send". Searching in the code I find the following: https://github.com/apache/airflow/blob/944dcfbb918050274fd3a1cc51d8fdf460ea2429/airflow/models/taskinstance.py#L1719 What this shows is: ``` if email_for_state and task.email: try: self.email_alert(error) except Exception: self.log.exception('Failed to send email to: %s', task.email) ``` what this means is that if an exception occurs while sending an email, all we get is a "Failed to send" error and the diagnostics of why we failed to send have been lost. ### What you expected to happen I would like to see additional debuging on why the email failed to send. Presumably this would be the exception text from the underlying call to send an email. ### How to reproduce _No response_ ### Anything else _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
