On the vps where I host a django website, I have set up a postfix mailserver to be used by django for email. The mailserver works. Using mutt on the vps command line, I can send and receive mail to/from other accounts like gmail etc.
Still, I am having trouble using postfix to send mail from django.
I followed the advice in https://stackoverflow.com/a/28143166/1009979, with settings...
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'localhost'
EMAIL_PORT = 25
EMAIL_HOST_USER = ''
EMAIL_HOST_PASSWORD = ''
EMAIL_USE_TLS = False
When I try
>>> from django.core.mail import send_mail
>>> send_mail('Subject here', 'Here is the message.', 'from@example.com', ['andrews.markw@gmail.com'])
I get
Traceback (most recent call last):

SMTPRecipientsRefused: {u'andrews.markw@gmail.com': (550, '5.7.1 <vps7718.webhosting.uk.com>: Helo command rejected: Host not found')}
When I google for advice about SMTPRecipientsRefused: or Helo command rejected: Host not found, no obvious solutions to my problems arise.
Is there something wrong with the settings?
I should mention that I have no general problem problem with django email. For example, I can send gmail emails from django (following settings and procedure described here https://stackoverflow.com/a/23402208/1009979).
