Question

I get the following exception when I try to send an email:

Traceback (most recent call last):
  my_own_functions ...
  File "C:\Python27\lib\site-packages\django\core\mail\message.py", line 248, in send
    return self.get_connection(fail_silently).send_messages([self])
  File "C:\Python27\lib\site-packages\django\core\mail\backends\smtp.py", line 92, in send_messages
    sent = self._send(message)
  File "C:\Python27\lib\site-packages\django\core\mail\backends\smtp.py", line 110, in _send
    email_message.message().as_string())
  File "C:\Python27\lib\smtplib.py", line 733, in sendmail
    raise SMTPRecipientsRefused(senderrs)
SMTPRecipientsRefused: {'aaa': (553, "5.1.2 We weren't able to find the recipient domain. Please check for any\n5.1.2 spelling errors, and make sure you didn't enter any spaces, periods,\n5.1.2 or other punctuation after the recipient's email address. q10sm6381464wie.2")}

I want to catch that exception and have tried:

try:
    sendActivationEmail()
except SMTPRecipientsRefused:
    return "error"

However, that gives me an “undefined variable” error. It’s not recognizing SMTPRecipientsRefused. In Eclipse it says “Undefined variable: SMTPRecipientsRefused”

Answer 1

An exception is just like any other class in Python: you need to import it into your code before you can reference it. You need from smtplib import SMTPRecipientsRefused.
