Django send_mail无法正常工作，并返回0个错误

Question

My code executes fine from my localhost. However, when I try and run my django program from an ubuntu 16.04 server it doesn't work. I tried running the program in the shell and it doesn't return any errors. When I check my inbox I don't receive an email from the "from" address.

I've tried sending the email to different addresses. I've also tried sending it using TLS instead of SSL. I also tried using smtplib to send the email instead of using django's send_mail.

Here is my code I'm using to send the email

send_mail('subject','my message','from_email@gmail.com',['to_email@xxxx.com'],fail_silently=False)

Here is my settings.py file

EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = 'from_email@gmail.com'
EMAIL_HOST_PASSWORD = '*******'
EMAIL_PORT = 465

Answer 1

You're missing a couple settings that Django/Gmail require. Make sure to define EMAIL_BACKEND.

Additionally for port 465 you need to enable SSL which is disabled by default. https://docs.djangoproject.com/en/2.2/ref/settings/#email-use-ssl

EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = 'from_email@gmail.com'
EMAIL_HOST_PASSWORD = '*******'
EMAIL_PORT = 465
EMAIL_USE_SSL = True

Alternatively you can use TLS on 587

EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = 'from_email@gmail.com'
EMAIL_HOST_PASSWORD = '*******'
EMAIL_USE_TLS = True
EMAIL_PORT = 587

Answer 2

One of the issues I encountered when using Gmail is that Gmail blocked the website from accessing it because the IP address was unrecognized and Gmail thought that someone had broken into my account.

Have you checked your account for alerts you may need to deal with? We spent hours before doing that ourselves.
