Django的; 從我自己的postfix郵件服務器發送電子郵件

Question

在托管django網站的vps上，我設置了一個后綴郵件服務器，供django用於發送電子郵件。 郵件服務器正常工作。 在vps命令行上使用mutt，我可以向其他帳戶（例如gmail等）收發郵件。

但是，我仍然無法使用postfix從django發送郵件。

我遵循https://stackoverflow.com/a/28143166/1009979中的建議進行設置...

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'localhost'
EMAIL_PORT = 25
EMAIL_HOST_USER = ''
EMAIL_HOST_PASSWORD = ''
EMAIL_USE_TLS = False

當我嘗試

>>> from django.core.mail import send_mail
>>> send_mail('Subject here', 'Here is the message.', 'from@example.com', ['andrews.markw@gmail.com'])

我懂了

Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/home/andrews/development/wilhelm-development/local/lib/python2.7/site-packages/django/core/mail/__init__.py", line 62, in send_mail
    return mail.send()
  File "/home/andrews/development/wilhelm-development/local/lib/python2.7/site-packages/django/core/mail/message.py", line 303, in send
    return self.get_connection(fail_silently).send_messages([self])
  File "/home/andrews/development/wilhelm-development/local/lib/python2.7/site-packages/django/core/mail/backends/smtp.py", line 107, in send_messages
    sent = self._send(message)
  File "/home/andrews/development/wilhelm-development/local/lib/python2.7/site-packages/django/core/mail/backends/smtp.py", line 123, in _send
    self.connection.sendmail(from_email, recipients, message.as_bytes(linesep='\r\n'))
  File "/usr/lib/python2.7/smtplib.py", line 733, in sendmail
    raise SMTPRecipientsRefused(senderrs)
SMTPRecipientsRefused: {u'andrews.markw@gmail.com': (550, '5.7.1 <vps7718.webhosting.uk.com>: Helo command rejected: Host not found')}

當我用google搜索有關SMTPRecipientsRefused:建議或Helo command rejected: Host not found ，沒有明顯的解決方案出現。

設置有問題嗎？

我應該提一下，django電子郵件沒有任何一般性問題。 例如，我可以從Django發送gmail電子郵件（遵循此處描述的設置和過程https://stackoverflow.com/a/23402208/1009979 ）。

請確保您有permit_mynetworks在smtpd_helo_restrictions和smtpd_recipient_restrictions在/etc/postfix/main.cf
