Python / Django：发送电子邮件产生535（用于gmail电子邮件的工作）

Question

为了发送表单，我在AJAX中有一个脚本，它运行电子邮件触发器功能。返回以下错误：

EMAIL_HOST='mail.example.com'
EMAIL_HOST_USER='no-reply@example.com'
EMAIL_HOST_PASSWORD='xxx'
EMAIL_PORT='25'

为了发送表单，我在AJAX中有一个脚本，它运行电子邮件触发器功能。返回以下错误：

SMTPAuthenticationError at /vendas/contato/
(535, 'Incorrect authentication data')
Request Method: POST
Request URL:    http://example.com/vendas/contato/
Django Version: 1.3
Exception Type: SMTPAuthenticationError
Exception Value:

经过一些测试后，我发现在向gmail电子邮件发送邮件时，它会正常发送，example.com或example.net等其他区域会生成error 535。< / p>

有没有人知道造成这种情况的原因是什么？
