Python / Django: sending emails resulting in 535 (gmail working)

Question

I have a contact form where I send the message to the system administrator informing him about it. Email configuration information is fully verified and correct.

EMAIL_HOST='mail.xxx.net'
EMAIL_HOST_USER='[email protected]'
EMAIL_HOST_PASSWORD='xxx'
EMAIL_PORT='25'

To send the form I have a script in AJAX, which executes the function of triggering the email. The following error is returned:

SMTPAuthenticationError at /vendas/contato/
(535, 'Incorrect authentication data')
Request Method: POST
Request URL:    http://xxx.net/vendas/contato/
Django Version: 1.3
Exception Type: SMTPAuthenticationError
Exception Value:

After a few tests, I checked that when entering an email from gmail for example, email is normally sent, other domains such as xxx.net or yyy.com.br result in error 535.

Does anyone have any idea what might be causing this?

Answer 1

This is your smtp service authentication error.

It’s not just putting in another host domain and another user and that’s it. You have to look at the documentation of the new smtp service, see what is the host address and the port to be used.
