server.close()

Answer 1

You may have left the Gmail account with block less secure apps on. This means Gmail will reject email sent by any less secure programs, and block your email. I highly recommend this tutorial , which will go through everything from setting up your Gmail account for the program.

Answer 2

Try the send method below:

import smtplib,ssl

def connect(username):
    serverName = username[username.index("@")+1:username.index(".")]
    while True:
        try:
            server = smtplib.SMTP(serverDict[serverName])
        except smtplib.SMTPException as error:
            print(error)
            continue
        try:
            server.ehlo()
            if server.has_extn("starttls"):
                server.starttls()
                server.ehlo()
        except (smtplib.SMTPException,ssl.SSLError) as error:
            print(error)
            disconnect(server)
            continue
        break
    return server

def disconnect(server):
    try:
        server.quit()
    except smtplib.SMTPException as error:
        print(error)

def send(username,password,message):
    server = connect(username)
    try:
        server.login(username,password)
    except smtplib.SMTPException as error:
        print(error)
    else:
        server.sendmail(username,password,message)
    disconnect(server)

serverDict = {
    "gmail"  :"smtp.gmail.com",
    "hotmail":"smtp.live.com",
    "yahoo"  :"smtp.mail.yahoo.com"
}

settings.py

...
...
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_USE_TLS = True
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = 'pruebadjangomail@gmail.com'
EMAIL_HOST_PASSWORD = '********'
EMAIL_PORT = 587

I'd used a Django signal to send massive emails, like this

signals.py

context = {'event': instance,
           'alarm': instance.alarm,
           'user': user,
           'device': instance.device,
           'var': instance.variables,
           'content_type': instance.content_type.all()}
plain_text = get_template('mail.txt')  # Plain text template
text_content = plain_text.render(context)
subject = 'Event Alert: ' + instance.__str__()
from_email = 'noreply@localhost.com'
to = email
msg = EmailMultiAlternatives(subject, text_content, from_email, [to])
try:
   if sub['staff_template'] is not None:
      htmly = get_template(sub['staff_template'])  # Define the HTML template
       html_content = htmly.render(context)  # Rendering the templates with context information
   elif sub['staff_template_text'] != "":
      htmly = Template(sub['staff_template_text'])
      html_content = htmly.render(Context(context))
   elif sub['user_template'] is not None:
      htmly = get_template(sub['user_template'])  # Define the HTML template
      html_content = htmly.render(context)  # Rendering the templates with context information
   elif sub['user_template_text'] != "":
      htmly = Template(sub['user_template_text'])
      html_content = htmly.render(Context(context))
   msg.attach_alternative(html_content, 'text/html')
   msg.send()
except:
   msg.send()
   print('Mail send to %s' % email)

I suggest to use Django tools to do that, here the docs
