django related to host mail - django-views

Question

Problem is related to host mail address as it cannot be changed and because of fixed host name, the sender’s mail address is not being updated after updating it several times
The problem with SendinBlue is that it does not allow us to use attachments with mail and ignores the attachments every time while sending an email
While using react for frontend, it saved the data from mails and does not send the mail from the backend through API.
def send_mail(request):
# form = emailssForm()
if request.method == 'POST':
name = request.POST.get('name')
email = request.POST.get('email')
message = request.POST.get('message')
subject = request.POST.get('subject')
from_email = request.POST.get('from_email')
# file = request.POST.get('file')
template = loader.get_template('contact_form.txt')
context = {
'name': name,
'email': email,
'message': message,
'subject': subject,
'from_email':from_email,
# 'file' : file,
}
message = template.render(context)
email = EmailMultiAlternatives(
"Uthara Print", email,message,
"Compny " + "Uthara Print",
['pandayharsh472#gmail.com',email]
)
# msg = EmailMultiAlternatives(
# subject,message,name,[from_email],
# )
email.content_subtype = 'html'
file = request.FILES['file']
email.attach(file.name, file.read(), file.content_type)
email.send()
messages.success(request, 'Message sent successfully ! I will ansewr you as soon as possibile....')
return HttpResponseRedirect('/')
