Test SMTP credentials using Python

You can run that test code directly in your local machine using a Python shell or by saving it into a .py file and running it from the terminal.

✅ Option 1: Run it in Python Shell (REPL)

1. Open your terminal or command prompt.
2. Start the Python shell:

 python 

1. Paste the code line by line:

import smtplib server = smtplib.SMTP('smtp.gmail.com', 587) server.starttls() server.login('backendsendeffr2@gmail.com', 'axifabumqxffftmnuyf') print("Login success!") server.quit() 

If it prints Login success!, the SMTP connection is working, and the issue is likely within your Django project config or a firewall block specific to that process.

✅ Option 2: Save and Run as a Python File

1. Create a file, e.g., smtp_test.py.
2. Paste the code:

import smtplib server = smtplib.SMTP('smtp.gmail.com', 587) server.starttls() server.login('backendsendeffr2@gmail.com', 'axifabumqxffftmnuyf') print("Login success!") server.quit() 

1. Run it in your terminal:

python smtp_test.py 

✅ Option 3: Save and Run as a Python File

To test if Django can send mail:

python manage.py shell 

Then paste:

from django.core.mail import send_mail send_mail( 'Test Subject', 'This is the test message.', 'backendsender2@gmail.com', # From email  ['your_email@example.com'], # To email  fail_silently=False ) 

If it succeeds, you’ll get an email. If it fails, it will show the real error.

🔍 What This Tells You

• If it succeeds, your credentials and Gmail settings are correct, and the issue lies in how Django is attempting to connect (firewall, TLS settings, or environmental variable parsing).
• If it fails with the same ConnectionRefusedError, your local machine is blocking the connection — usually a firewall, antivirus, or network setting.
