Logging stops if there are errors sending emails to admins

[coleslaw481]

Recently we hit a limit on sending emails via SMTP:

smtplib.SMTPDataError: (550, b'5.4.5 Daily user sending quota exceeded. v7sm11267272pjk.37 - gsmtp')

Two problems with this:

• Users and or Admins do not get any emails
• Internal logging of errors in Django App stops

The fix might be as simple as setting fail_silently to True in the config or might require a custom email backend that can handle send errors without causing the file system logger to stop.
