> Sending email with no AUTH fails
> --------------------------------
>
> Key: AIRFLOW-734
> URL: https://issues.apache.org/jira/browse/AIRFLOW-734
> Project: Apache Airflow
> Issue Type: Bug
> Components: utils
> Affects Versions: Airflow 1.8
> Reporter: Chris Riccomini
> Assignee: Chris Riccomini
>
> While running 1.8.0a2, we noticed that emails no longer worked for us. We
> have these settings:
> {noformat}
> [smtp]
> smtp_host = our.relay.com
> smtp_starttls = False
> smtp_ssl = False
> smtp_port = 2525
> smtp_mail_from = [email protected]
> {noformat}
> We are seeing:
> {noformat}
> [2017-01-05 15:10:13,666] {models.py:1378} ERROR - SMTP AUTH extension not
> supported by server.
> Traceback (most recent call last):
> File "/usr/lib/python2.7/site-packages/airflow/models.py", line 1374, in

> {noformat}
> It appears that the SMTP lib is trying to run the login() command in this
> code:
> {code:python}
> if not dryrun:
> s = smtplib.SMTP_SSL(SMTP_HOST, SMTP_PORT) if SMTP_SSL else
> smtplib.SMTP(SMTP_HOST, SMTP_PORT)
> if SMTP_STARTTLS:
> s.starttls()
> if SMTP_USER and SMTP_PASSWORD:
> s.login(SMTP_USER, SMTP_PASSWORD)
> logging.info("Sent an alert email to " + str(e_to))
> s.sendmail(e_from, e_to, mime_msg.as_string())
> s.quit()
> {code}
> Even though we have no user/pass set. This didn't happen in 1.7.1.2. I also
> tried setting:
> {noformat}
> smtp_user = False
> smtp_password = False
> {noformat}
> But this didn't help. Finally, I commented these lines out of the email
> email.py file:
> {noformat}
> #if SMTP_USER and SMTP_PASSWORD:
> # s.login(SMTP_USER, SMTP_PASSWORD)
> {noformat}
> The commenting worked. This suggests that the SMTP_USER and SMTP_PASSWORD are
> defaulting to a non-False value, and trying to force them to be false isn't
> working.
