Multiple mail connection

[spookylukey]

I'm afraid I can't understand your question. EMAIL_CONNECTIONS is not a standard Django setting. Are you using an extension that uses this? If so, please let me know what this extension is, or show more of your code that is actually using this.

You're right. EMAIL_CONNECTIONS is a custom setting of my app that I use to define multiple mail config and assign to connection param on send_mail function (https://docs.djangoproject.com/en/1.10/topics/email/#send-mail).

I've used this solution because I need to send mail from different account.
Now, my problem is that in case SMTP fail the mail is lost and your solution is perfect because store mail in DB and delivery is managed by cron job.

But I need to use different SMTP account.
Do you think it's possible ?

Thank you.

Salvo.

It depends on how you decide which connection to use.

First, work out whether it is possible to write your custom connection/send_mail logic as a custom email backend - https://docs.djangoproject.com/en/1.10/topics/email/#defining-a-custom-email-backend - this will be possible, for example, if you can tell just by examining the message (e.g. the from/to address) which SMTP details are needed. If the decision of which backend to use is made using contextual information from the calling code that isn't stored in the message itself, you will have difficulties.

If if it possible, then first write that backend and refactor your code to use it. Then simply install django-mailer and use a custom backend as described here https://github.com/pinax/django-mailer/blob/master/docs/usage.rst#usage :

EMAIL_BACKEND = "mailer.backend.DbBackend"
MAILER_EMAIL_BACKEND = "your.custom.EmailBackend"

Yes, I think to use from_address to route mail over multiple account.
I didn't see the MAILER_EMAIL_BACKEND setting. Can be perfect for what I need to do.

Thank you.
