django 发送邮件认证错误 但是使用 stmp 模块没有问题，怎么回事？

使用 django 发邮件一直报认证错误 (535, 'Error: authentication failed')，但是用 stmp 模块登录发送邮件没有问题，使同一个账户，密码也使用一样的，但是用 django 发送的时候会报错怎么回事？ stmp 代码如下，可以正常的发送

 msg['to'] = '[email protected]' msg['from'] = '[email protected]' msg['subject'] = 'receive or ship parts' try: server = smtplib.SMTP('smtp.163.com') server.login('[email protected]','xxxxx555') server.sendmail(msg['from'],msg['to'],msg.as_string()) server.quit() print 'successfully' except Exception, e: print str(e) if __name__=='__main__': sendmail(item_list,meta_dict) 

django setting 代码如下：

EMAIL_USE_TLS = True EMAIL_HOST = 'smtp.163.com' EMAIL_HOST_USER = '[email protected]' EMAIL_HOST_PASSWORD = 'xxxxx555' EMAIL_PORT = 25 

email 函数如下：

template_html = get_template('email.html') cOntext= Context({'user': user, 'other_info': info}) if not user.e try: subject, from_email, to = 'hello world', '[email protected]', '[email protected]' text_cOntent= 'This is an import message.' html_cOntent= '<p>This is an <strong>important</strong> message.</p>' msg = EmailMultiAlternatives(subject, text_content, from_email, [to]) msg.attach_alternative(html_content, "text/html") msg.send() print 'sucessful' except Exception, e: print 'failed', e
