SMTP AUTH extension not supported by server - Sending emails through a private host

Question

I registered a domain and a private email using namecheap.com. I am trying to send an email from this private email. However, I get the error in the title.

In my settings.py, I have these settings:

EMAIL_HOST = 'mail.privateemail.com'
EMAIL_HOST_USER = 'contact@mysite.com'
EMAIL_HOST_PASSWORD = 'my password'
EMAIL_PORT = 587
EMAIL_USE_TLS = False
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
DEFAULT_FROM_EMAIL = EMAIL_HOST_USER

And I am trying to send my mail through a view:

send_mail(
    'Subject here',
    'Here is the message.',
    'contact@mysite.com',
    ['myname@gmail.com'],
    fail_silently=False,
)

I get this error :

SMTP AUTH extension not supported by server.

Answer 1

This is happening because you have conflicting settings:

EMAIL_PORT = 587        # Port 587 is reserved for TLS
EMAIL_USE_TLS = False   # But you have disabled TLS

You either need to set EMAIL_USE_TLS to True or use the default port for unencrypted connections (25).

I was searching answer for this since 4 hours. I still dont know why this configuration works for me, but yes, IT WORKS for me.

I simply removed,

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

from my settings.py, and add below configuration in settings.py

EMAIL_HOST = 'smtp.gmail.com'

EMAIL_HOST_USER = 'username@domain.com'

EMAIL_HOST_PASSWORD = 'mypassword'

EMAIL_PORT = 587

EMAIL_USE_TLS = True

Answer 3

Remove the following config since "SMTP AUTH extension not supported by" your EMAIL_HOST:

EMAIL_HOST_PASSWORD = 'my password'
EMAIL_PORT = 587

Answer 4

I was using a server that is not Gmail by default and turns out to be a port issue, I found that I was using the wrong port, I changed it to 465 for SMTP with TLS, Thanks to this link..

So here are the settings I used:

EMAIL_PORT = 465       
EMAIL_USE_TLS = True
