Resolving Email Sending Problems in Django

Improving Django's Email Functionality

Python Django Configuration

from django.core.mail import EmailMessage
from django.conf import settings
from django.template.loader import render_to_string
from django.utils.http import urlsafe_base64_encode
from django.utils.encoding import force_bytes
from .tokens import account_activation_token
from django.contrib.sites.shortcuts import get_current_site
def send_verification_email(request, user):
    current_site = get_current_site(request)
    subject = 'Activate Your Account'
    message = render_to_string('acc_active_email.html', {
        'user': user,
        'domain': current_site.domain,
        'uid': urlsafe_base64_encode(force_bytes(user.pk)).decode(),
        'token': account_activation_token.make_token(user)
    })
    email = EmailMessage(subject, message, to=[user.email])
    email.send()

Django Email Troubleshooting Backend Script

Python Code for SMTP Troubleshooting

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
def test_smtp_server(user_email, host, port, use_tls=True, username=None, password=None):
    try:
        server = smtplib.SMTP(host, port)
        if use_tls:
            server.starttls()
        server.login(username, password)
        msg = MIMEMultipart()
        msg['From'] = username
        msg['To'] = user_email
        msg['Subject'] = 'SMTP Connection Test'
        message = 'This is a test email sent by Django server to check SMTP configuration.'
        msg.attach(MIMEText(message, 'plain'))
        server.send_message(msg)
        server.quit()
        print("SMTP server is working properly.")
    except Exception as e:
        print("Failed to connect to SMTP server. Error: {}".format(e))

9. Can asynchronous emails be sent with Django?

Important Lessons Learned from Debugging Django's Email Functionality

This investigation into Django's email sending problems offers workable fixes and emphasizes the significance of accurate setting and sophisticated handling methods. Web developers can improve the resilience of their web applications' email capabilities and avoid frequent mistakes by being aware of the underlying SMTP settings and taking asynchronous email sending into account.
