Simple, powerfull and nonobstructive django email middleware.

djmail

djmail is a BSD Licensed, simple and nonobstructive django email middleware.

Why use djmail? Because it:

• Sends emails asynchronously without additional libraries.
• Sends emails using celery tasks.
• Can retry sending failed messages (with cron task or celery periodic task).
• Can assign delivery priority.
• Has a powerful class to build emails from templates.
• Works transparently (works as middleware for native django email backends)

djmail was created by Andrey Antukh (@niwinz) and is maintained by David Barragán (@bameda).

djmail's Issues

Tests fails in django 1.10

Hello,

During #32 pull requests I identified uncompatibility with django 1.10 with following erros:

dns resolution failure for EMAIL_HOST blackholes messages

I ran into an issue where the DNS entry for the specified host stopped resolving to anything. In this case, all messages marked for sending ended up with a status of draft. I'm assuming that's because djmail knew better than try to send them in the first place, which is fine. The problem is that there was no way for me to resend once the underlying issue was resolved without manually updating the status to something that the resend management command could use (I chose pending).

Problem with templates without the body-text version

If I only have the body-html version of the template, this doesn't work correctly, the mails apear in the mail client in text but his content is HTML.

Rendering of HTML content

The html content of an email is displayed as code.

It would be much more useful to see the rendered html.

The possibility to see the raw html is great. It should just not be the default output.

class NoArgsCommand removed in django 1.10

https://docs.djangoproject.com/en/1.10/releases/1.10/#features-removed-in-1-10

The class BaseCommand should be used instead: https://docs.djangoproject.com/ja/1.10/internals/deprecation/#deprecation-removed-in-1-10

Note:

Subclassing the BaseCommand class requires that you implement the handle() method.

https://docs.djangoproject.com/ja/1.10/howto/custom-management-commands/#django.core.management.BaseCommand

Message.from_email_message stores HTML in field body_text

Body is not always text/plain but sometimes text/html 746236d.
However this https://github.com/niwibe/djmail/blob/master/djmail/models.py#L67 always sets body_text to email.body even if this is text/html.

Celery backend fails when CELERY_TASK_SERIALIZER not defined

Celery defaults the setting CELERY_TASK_SERIALIZER to 'picke' so there is no guarantee that a Django project will set it.

Infinite when trying to send emails without specyfing FROM_EMAIL

Hi

I forgot to put DEFAULT_FROM_EMAIL = EMAIL_HOST_USER to simplify email sending.

It caused a big problem - email sending went into an infinite loop which caused to generate over 5000 email objects in the database.

Docs site is down

The GitHub Pages site that hosts the documentation no longer exists: http://bameda.github.io/djmail/

obtain Message instance after email send

I am implementing a Notifications feature and I'd like to connect the notification with the email sent, for that I included something like the following to my Notification model.

email_message = models.OneToOneField(
    djmail_models.Message,
    on_delete=models.SET_NULL,
    null=True,
    blank=True,
    verbose_name=_("Email message"),
)

But I don't know how to later match this, the only thing that I was able to come up with was:

self.email_message = djmail_models.Message.objects.filter(
        body_html__icontains=self.id
    ).first()

But that is not optimal, is there a way to get the uuid or model instance for example when the email is sent? or how should I go about doing this? I send the email this way:

email_builder = template_mail.MagicMailBuilder()
context = {
    ...
}
email = email_builder.notification(self.recipient, context)
email.send() # <---------- it would be cool to have something like "djmail_message = email.send()"

Migration missing?

Celery backend: Handle other serializers than pickle (JSON)

When switching to the Celery back-end I have an issue: The parameters for the task, "emails" are instances of django.core.mail.message.EmailMessage or EmailMultiAlternatives. There are both not serializable to JSON. We do not use pickle as recommended by Celery's documentation.

I will look at it tomorrow but in the meantime if you have any idea to fix it, thanks for sharing.
