Django форма обратной связи на почту

Подскажите что не правильно, форма не отсылает данные на почту

settings.py

EMAIL_USE_TLS = True
EMAIL_HOST = 'mail.hosting.reg.ru'
EMAIL_PORT = 465
EMAIL_HOST_USER = '[email protected]'
EMAIL_HOST_PASSWORD = 'password'

models.py

class ContactForm(forms.Form):
    name = forms.CharField(max_length=100, required=True)
    phone = forms.CharField(max_length=100, required=True)
    message = forms.CharField(widget=forms.Textarea, required=True)

views.py

def contactform(request):
    if request.method == 'POST':
        form1 = ContactForm(request.POST)
        # Если форма заполнена корректно, сохраняем все введённые пользователем значения
        if form1.is_valid():
            name = form1.cleaned_data['name']
            phone = form1.cleaned_data['phone']
            message = form1.cleaned_data['message']
            try:
                send_mail(name, phone, message, ['[email protected]'])
            except BadHeaderError:
                return HttpResponse('Invalid header found.')
            return redirect('success')
    else:
        form1 = ContactForm()
    return render(request, 'index.html', {'form1': form1})

index.html
