Django - [Errno 111] Connection refused

Question

when I post a comment, do not save, crashes (error: [Errno 111] Connection refused), why?

thanks!

Answer 1

Looks like you are trying to send a mail (send_mail()) and your mail settings in your settings.py are not correct.

You should check the docs for sending emails.

---

For debugging purposes you could setup a local smtpserver with this command:

python -m smtpd -n -c DebuggingServer localhost:1025

and adjust your mail settings accordingly:

EMAIL_HOST = 'localhost'
EMAIL_PORT = 1025

This is documented here: Testing e-mail sending

As an alternative to starting a dedicated debugging server you could use the console.EmailBackend which was added to Django recently.

Answer 2

For Development and Testing:

In Django 1.6+ we can just add this line in settings.py

EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'

This will display the mail on the console for Easy Verification.

Note: Mail will not be sent to the specified recipient in Msg.Its just for Development and Testing.

For that you need to configure SMTP server which is given in the Doc.
