E-Mails are not sending & manage.py in the wrong place

[fshubthunfischbaum]

Describe the issue
MediaCMS is not sending any E-Mails.

To Reproduce
Steps to reproduce the issue:

1. Enter E-Mail Server details
2. Register New User, no E-Mail

Expected behavior
Expecting the User to receive the registration E-Mail

Environment (please complete the following information):

• OS: Ubuntu 20.04.5 LTS (GNU/Linux 5.4.0-125-generic x86_64)
• Singleserver
• Firefox

Additional context
Could not test with the manage.py shell. Unable to load Django interface.
That manage.py is also not in the right folder. I did not move it, but the troubleshooting guide is based on different folder paths.
My location of the manage.py file: /home/mediacms.io/mediacms.py

I'm not sure, but there is a SSL Bug with a Version of smtplib of Python. Is this the issue for my installation as well?
I sent out an E-Mail without SSL/TLS. That went successfully.

Hey everyone,
this is still an issue for us and is thus preventing our video platform from launch. Any help would be appreciated.
Thanks :)

Hi, what is the account provider you are using (eg Gmail, Mailgun etc)
And what are the logs? Can you do a tail -f logs/celery* , then try to send an email (eg use the forgot password) and paste here the error?

[fshubthunfischbaum]

Hi again! Thanks for your reply.
We are using our own Mail Service, just plain smtp.

Output from the celery log:
Invalid HTTP_HOST header: '${ip}:${port}'. The domain name provided is not valid according to RFC 1034/1035.
The mailserverhost entered is mail.fshub.io with a 587 as port. This is the config:

DEFAULT_FROM_EMAIL = 'tube@removed'
EMAIL_HOST_PASSWORD = 'supersecretpasswordhere'
EMAIL_HOST_USER = 'tube@removed'
EMAIL_USE_TLS = True
SERVER_EMAIL = 'tube@removed'
EMAIL_HOST = 'removed'
EMAIL_PORT = 587

We should be good, right?

Edit: removed server details for privacy reasons.

Hi, I'm not sure how this error is related with the email settings - which look good btw.

Can you share the complete trace?

Also there are some instructions here https://github.com/mediacms-io/mediacms/blob/main/docs/admins_docs.md#15-debugging-email-issues that will help find the real problem, can you try that?

[fshubthunfischbaum]

My manage.py is located /home/mediacms.io/mediacms$
is that correct?

[mgogoulos]

correct

uwe@fvidspace:/$ source /home/mediacms.io/bin/activate
uwe@fvidspace:/$ cd  mediacms
uwe@fvidspace:/mediacms$ python manage.py shell

[fshubthunfischbaum]

It returns 1.
This should mean that everything went fine?

I am running into the same issue as OP. My setup is exactly the same.

SMTP Server details in configuration file are fine, I have triple checked them. I ran the test using the debugging instructions, and the email was sent successfully, which I take it to mean the credentials are good in the settings file, my network allows outbound messages and the smtp server is properly sending the message.

However, when trying to register a user, an email is not sent. Here is the error I see in the log: Cannot reach celery_email_backend

Any help is appreciated.

[ EDIT: SOLVED - A server reboot of the OS helped to resolve issue. I guess the systemctl restart command was not covering all services that needed to be restarted after the configuration changes]

[fshubthunfischbaum]

The restart helped for me as well. Thank you @rbpawdev !
