Defining a custom email backend

[Sujata Aghor]

Hello Everyone,

I want to use different values of - EMAIL_HOST_USER & EMAIL_HOST_PASSWORD for each of my users. I will take those values from database and not from settings.py

In django documentation I can see only a single paragraph about defining a custom email backend, which is not giving me enough ideas.

If I Try to change value of EMAIL_HOST_USER in script, it gives me below error - 

send_mail() got an unexpected keyword argument 'EMAIL_HOST_USER'

How to change these two values in a script?

Can anyone help here please.

settings.py : 

DEFAULT_FROM_EMAIL = '*****************'

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_USE_TLS = True
EMAIL_PORT = ***
EMAIL_HOST_USER = '*********************"
EMAIL_HOST_PASSWORD = '***********"

script.py :

from_email = DEFAULT_FROM_EMAIL
vars_dict = dict(tasks=usr_tasks,
                     reminder=reminder,
                     reseller=reseller,
                     logo=logo,
                     host=host,
                     )

# get values: r_email and r_pass specific to this reseller
        r_obj = Reseller.objects.get(id=rid)
        r_email = r_obj.remail if r_obj.remail else None
        r_pass = r_obj.rpass if r_obj.rpass else None  

        html_message = loader.render_to_string(
            template,vars_dict)

        if subject and message and from_email:
            print("Sending mail to %s"%recipient)
            try:
                if r_email and r_pass:
                    send_mail(subject,message,from_email,recipient,fail_silently=True, EMAIL_HOST_USER=r_email,
                    EMAIL_HOST_PASSWORD=r_pass, html_message=html_message)
                else:  
                    send_mail(subject,message,from_email,recipient,fail_silently=True,html_message=html_message)
            except Exception as e:
                print(e)
            else:
                print("Mail sent successfully!")

---------------------------------------------------------------------------------------------------------------------------------

Roughly this is my code.

in line -  send_mail(subject,message,from_email,recipient,fail_silently=True, EMAIL_HOST_USER=r_email,

                    EMAIL_HOST_PASSWORD=r_pass, html_message=html_message)

its giving me error - send_mail() got an unexpected keyword argument 'EMAIL_HOST_USER'

Can you suggest anything about this ?

Thanks

You can create your own connection and then pass to send_mail()

connection = get_connection(host=my_host, 
                            port=my_port, 
                            username=my_username, 
                            password=my_password, 
                            use_tls=my_use_tls) 

send_mail('subject', 'test message', 'from_email', ['to'], connection=connection)
