我在Django 2.0上构建了一个应用程序并部署到pythonanywhere.com。由于Pythonanywhere.com托管没有SMTP服务器，我使用外部服务器（使用hostiq.com SMPT服务器，我托管其他网站）使用视图发送消息。一切都很好，除了价格:)
所以我把应用程序移动到reg.ru主机（因为它很便宜并且有SMTP服务器）。 Web应用程序工作正常，但发送邮件的链接除外。使用发送邮件的所有veiws功能，失败并给出错误“从应用程序收到不完整的响应”。您可以通过以下链接自行测试：http://www.tajadventures.com/contact-us/
可能有助于解决问题的更多信息：
1）我在共享主机reg.ru中有两个应用程序。 2）我在服务器上使用虚拟环境; 3）客户支持表示在共享主机中不允许使用PROXY（如此Working with django : Proxy setup）。 4）这是日志文件所说的内容（由客户支持发送）：
open("/opt/openssl/openssl11/cert.pem", O_RDONLY) = -1 ENOENT (No such file or directory)
stat("/opt/openssl/openssl11/certs/6a909d98.0", 0x7ffd3f0aebb0) = -1 ENOENT (No such file or directory)

stat("/opt/openssl/openssl11/certs/4a6481c9.0", 0x7ffd3f0aebb0) = -1 ENOENT (No such file or directory)

有没有办法解决这个错误？谢谢你的时间。
所以，我的问题的解决方案是从我的视图功能中删除Google的ReCaptcha。我目前的设置如下所示：
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_USE_TLS = False
EMAIL_HOST = 'server229.hosting.reg.ru'
EMAIL_PORT = 587
EMAIL_HOST_USER = '[email protected]'
EMAIL_HOST_PASSWORD = '********'
但我认为这个错误有很多原因，例如访问不存在的url等。
