我如何知道Django / Python是否正确发送了电子邮件？

Question

I need know that if a email is sent correctly for to do several operations but the function always return True.

Any idea?

Thanks you.

Answer 1

There is no way to check that a mail has actually been received. This is not because of a failing in Django, but a consequence of the way email works.

If you need some form of definite delivery confirmation, you need to use something other than email.

Answer 2

When running unit tests emails are stored as EmailMessage objects in a list at django.core.mail.outbox you can then perform any checks you want in your test class. Below is an example from django's docs .

from django.core import mail
from django.test import TestCase

class EmailTest(TestCase):
    def test_send_email(self):
        # Send message.
        mail.send_mail('Subject here', 'Here is the message.',
            'from@example.com', ['to@example.com'],
            fail_silently=False)

        # Test that one message has been sent.
        self.assertEqual(len(mail.outbox), 1)

        # Verify that the subject of the first message is correct.
        self.assertEqual(mail.outbox[0].subject, 'Subject here')

Alternatively if you just want to visually check the contents of the email during development you can set the EMAIL_BACKEND to:

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

and then look at you console.

or

EMAIL_BACKEND = 'django.core.mail.backends.filebased.EmailBackend'
EMAIL_FILE_PATH = '/tmp/app-messages' # change this to a proper location

then check the file.

这篇有关将Django与Postmark集成的文章描述了如何继续进行电子邮件传递。

Answer 4

In case of error, send_mail should raise an exception. The fail_silently argument makes possible to ignore the error. Did you enable this option by mistake?

I hope it helps
