Hi @Neurozone , I've converted this to a discussion as I believe it is a configuration issue

Have you set configuration as on https://github.com/mediacms-io/mediacms/blob/main/docs/Configuration.md#set-email-settings
? If in doubt, share configuration here (with any sensitive info obfuscated).

Hello @mgogoulos
Here a re my congi with obfuscated data
`

email settings

DEFAULT_FROM_EMAIL = "hecate.@gmail.com"
EMAIL_HOST_PASSWORD = ""
EMAIL_HOST_USER = "hecate.@gmail.com"
EMAIL_USE_TLS = True
SERVER_EMAIL = DEFAULT_FROM_EMAIL
EMAIL_HOST = "smtp.gmail.com"
EMAIL_PORT = 587
ADMIN_EMAIL_LIST = ["hecate.*@gmail.com"]
`

with gmail or my personnal smtp server

Did you manage to get through this?
If no, try to see if email settings are correct, thus we exclude the case of error credentials and have to see whether there is any other issue introduced

Enter the Django shell by running this:

source  /home/mediacms.io/bin/activate
python manage.py shell

then c/p the following (you might want to change the email to the one you are sending this test email to!)

from django.core.mail import EmailMessage
from django.conf import settings

settings.EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'

email = EmailMessage(
    'title',
    'msg',
    settings.DEFAULT_FROM_EMAIL,
    ['[email protected]'],
)
email.send(fail_silently=False)

If this breaks with an error, you are going to see the error - example upon providing error gmail credentials, this gives

SMTPAuthenticationError: (535, b'5.7.8 Username and Password not accepted. Learn more at\n5.7.8  https://support.google.com/mail/?p=BadCredentials d4sm12687785wrc.34 - gsmtp')

I fixed it by using this:

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'

Then i resovled authentication issues with this (might not be an issue with you)
EMAIL_USE_SSL = True
EMAIL_PORT = 465
