Answer 1

看起来你正在尝试发送邮件(send_mail())和您的邮件设置你settings.py是不正确的.

您应该查看发送电子邮件的文档.

出于调试目的,您可以使用以下命令设置本地smtpserver:

python -m smtpd -n -c DebuggingServer localhost:1025

并相应地调整您的邮件设置:

EMAIL_HOST = 'localhost'
EMAIL_PORT = 1025

这在此处记录:测试电子邮件发送

作为启动专用调试服务器的替代方法,您可以使用console.EmailBackend最近添加到Django的服务器.

Answer 2

用于开发和测试:

在Django 1.6+中,我们可以在settings.py中添加此行

EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'

这将在控制台上显示邮件以进行简易验证.

注意: 邮件不会发送到Msg.Its中的指定收件人,仅用于开发和测试.

为此,您需要配置Doc中给出的SMTP服务器.

供参考:用于发送电子邮件的Django文档

Answer 3

在您的服务器上安装postfix包,它的工作原理.如果是ubuntu,请尝试:

sudo apt-get install postfix

在您的设置中,放置:

EMAIL_HOST = 'localhost'

Answer 4

我们最近离开了Python调试电子邮件服务器,使用了一个名为Mailcatcher的程序.Mailcatcher作为守护进程运行,拦截所有测试电子邮件到端口1025,并与Web服务器集成,以便您可以从浏览器查看截获的电子邮件.好处

• 如果需要,您可以将测试电子邮件视为HTML
• 所有测试电子邮件的集中管理 - 它们会一直存在,直到您清除它们为止
• 查看来自任何浏览器的测试电子邮件,而不是滚动终端窗口

您可以在此处阅读更多内容并下载:http: //rubygems.org/gems/mailcatcher

如果您不喜欢Ruby,我的同事已经将Mailcatcher的功能移植到node.js - 请查看MailDev:http://djfarrelly.github.io/MailDev/

Answer 5

另外以下内容将有所帮助:

将以下最小设置放在服务器上的settings.py或local_settings.py文件中.

EMAIL_HOST = 'localhost'
EMAIL_PORT = 587
EMAIL_USE_TLS = True

而不是使用smtp.gmail.com,它有很多限制,你可以拥有自己的邮件服务器.

你可以通过安装自己的邮件服务器来实现:

sudo apt-get install sendmail
