Docker email not working when using null credentials

Troubleshooting
1

On docker when I try and send an email i see

./taiga-manage.sh test_emails myemail@me.com

Traceback (most recent call last):
  File "/taiga-back/manage.py", line 17, in <module>

however if i do

curl --url ‘smtp://smtp.mysmtp.com:25’ --mail-from ‘taiga-noreply@whatever.com’ --mail-rcpt ‘myemail@me.com’ ^Cupload-file mailtest.txt --insecure

I receive the email as expected.

The smtp server is a local one that doesn’t require user/password this is my current config

# Taiga's SMTP settings - Variables to send Taiga's emails to the users
EMAIL_BACKEND=smtp  # use an SMTP server or display the emails in the console (either "smtp" or "console")
EMAIL_HOST=smtp.mysmtp.com  # SMTP server address
EMAIL_PORT=25   # default SMTP port
EMAIL_HOST_USER=  # user to connect the SMTP server
EMAIL_HOST_PASSWORD= # SMTP user's password
EMAIL_DEFAULT_FROM=taiga-noreply@whatever.com  # default email address for the automated emails
# EMAIL_USE_TLS/EMAIL_USE_SSL are mutually exclusive (only set one of those to True)
EMAIL_USE_TLS=True  # use TLS (secure) connection with the SMTP server
EMAIL_USE_SSL=False  # use implicit TLS (secure) connection with the SMTP server

Hi @stretch

you should try to set TLS connection to False

EMAIL_USE_TLS=False

According to the documentation:

Whether to use a TLS (secure) connection when talking to the SMTP server. This is used for explicit TLS connections, generally on port 587.

I hope this can help

Best regards.

AttributeError: 'NoneType' object has no attribute 'invited_by'

and email is received but still errors as above

#EMAIL_HOST_USER= # user to connect the SMTP server
#EMAIL_HOST_PASSWORD= # SMTP user’s password

however after commenting that outand docker restart none of the existing projects show so i have to uncomment and restart again.
