Django Sendgrid Heroku setup

I use a Django / Sendgrid / Heroku setup which was working well but it stopped with no apparent reason.

my django settings:

EMAIL_HOST="smtp.sendgrid.net"
EMAIL_HOST_PASSWORD="..."
EMAIL_HOST_USER="..."
EMAIL_PORT=587
EMAIL_USE_TLS=True

with this settings, if I send simple emails with the django library...

from django.core.mail import send_mail 
send_mail(
    'Subject here',
    'Here is the message.',
    from_email_address,
    [to_email_address],
    fail_silently=False,
)

I get this error

--> SMTPServerDisconnected: Connection unexpectedly closed

I can still send emails using the sendgrid python library

import sendgrid 
sg = sendgrid.SendGridAPIClient(apikey)
sg.send(data)

Is there anything I am missing?

Solution

  • Just figured this out: Sendgrid dynamically provides a password through the SENDGRID_PASSWORD Heroku environment variable. However the variable used for the email settings is EMAIL_HOST_PASSWORD which was not updated after our password changed.

    Be sure that both variables are identical
