### Apache Airflow version 3.0.4 ### If "Other Airflow 2 version" selected, which one? _No response_ ### What happened? I have a working smtp & email setup for v.2.10. I recently ran v.3.0.4 but unable to use this smtp server. What's happening ⬇️ ### What you think should happen instead? _No response_ ### How to reproduce Since v.3, Airflow forces you to set up a connection for SMTP - either `smtp_default` or the one defined in `AIRFLOW__EMAIL__EMAIL_CONN_ID`. 1. If I don't create a connection, I get the following errors: ``` AirflowException: SMTP connection is not found. AirflowNotFoundException: The conn_id `smtp_default` isn't defined ``` 2. Then I create a connection, and since our SMTP server allows using without specifying a username and password, I leave these fields empty. <img width="784" height="693" alt="Image" src="https://github.com/user-attachments/assets/4475ce43-4a92-45f0-8410-5188263c6ce1"; /> All other settings come from environment variables: ``` AIRFLOW__EMAIL__EMAIL_BACKEND: 'airflow.utils.email.send_email_smtp' AIRFLOW__EMAIL__EMAIL_CONN_ID: 'smtp_default' AIRFLOW__EMAIL__FROM_EMAIL: '[email protected]' AIRFLOW__SMTP__SMTP_HOST: 'my.correct.smtphost' AIRFLOW__SMTP__SMTP_STARTTLS: 'true' AIRFLOW__SMTP__SMTP_SSL: 'false' AIRFLOW__SMTP__SMTP_PORT: 25 AIRFLOW__SMTP__SMTP_MAIL_FROM: '[email protected]' AIRFLOW__SMTP__SMTP_TIMEOUT: 30 AIRFLOW__SMTP__SMTP_RETRY_LIMIT: 5 ``` After that, create and run a task with EmailOperator: `SMTPServerDisconnected: please run connect() first` ``` File "/home/airflow/.local/lib/python3.12/site-packages/airflow/sdk/execution_time/task_runner.py", line 890 in run File "/home/airflow/.local/lib/python3.12/site-packages/airflow/sdk/execution_time/task_runner.py", line 1177 in _execute_task File "/home/airflow/.local/lib/python3.12/site-packages/airflow/sdk/bases/operator.py", line 397 in wrapper File "/home/airflow/.local/lib/python3.12/site-packages/airflow/providers/smtp/operators/smtp.py", line 89 in execute File "/home/airflow/.local/lib/python3.12/site-packages/airflow/providers/smtp/hooks/smtp.py", line 72 in __enter__ File "/home/airflow/.local/lib/python3.12/site-packages/airflow/providers/smtp/hooks/smtp.py", line 100 in get_conn File "/usr/local/lib/python3.12/smtplib.py", line 769 in starttls File "/usr/local/lib/python3.12/smtplib.py", line 611 in ehlo_or_helo_if_needed File "/usr/local/lib/python3.12/smtplib.py", line 451 in ehlo File "/usr/local/lib/python3.12/smtplib.py", line 378 in putcmd File "/usr/local/lib/python3.12/smtplib.py", line 365 in send ``` If I messed up anything, please guide me on the correct way to set up an SMTP in v.3.0.*.
