Django SMTPServerDisconnected error on password reset (but works elsewhere)

I'm trying to set up self-serve password resets on a django setup. I have configured it to use the in-built password reset system, and have tested everything on my dev machine, and works fine. However, in production (i.e. actually sending emails), when I try to get a password reset email, it throws an SMTPServerDisconnected error:

[22/Sep/2017 15:04:59] ERROR [django.request:256] Internal Server Error: /password_reset/

    return self.getreply()
  File "/usr/lib/python2.7/smtplib.py", line 368, in getreply
    raise SMTPServerDisconnected("Connection unexpectedly closed")
SMTPServerDisconnected: Connection unexpectedly closed

I'm using G-Suite (Google) as the SMTP relay; the settings I'm using are:

EMAIL_HOST = 'smtp-relay.gmail.com'  
EMAIL_PORT = 587                     
EMAIL_USE_TLS = True

The weird thing is I can send emails fine in other places within the system, using django's django.core.mail.send_mail() function.

The problem turned out to be that I hadn't set DEFAULT_FROM_EMAIL, thus django was attempting to send from a localhost email address, which Google's SMTP servers silently rejected. In other uses for send_mail() I had specified the from address, so this didn't appear as an issue there.
