用send_mail发送电子邮件时Django“错误填充”错误

我无法使用django.core.mail.send_mail函数发送电子邮件。用send_mail发送电子邮件时Django“错误填充”错误

用mail_admins和mail_managers发送邮件工作正常，所以我猜这个问题不是我的邮件配置。

我得到的

File "/usr/lib/python2.6/base64.py" in decodestring 
321.  return binascii.a2b_base64(s)

这是很奇怪的也是一个“不正确的填充”的错误，因为我的Django的服务器是一个的virtualenv中运行。完整回溯低于：

邮件正文的内容是什么样的？ – buckley

Base-64将3个字节（0-255范围内的回波）编码为4个字节（每个在范围内）。输出的长度为总是是4的多个（忽略空格）;该方法增加了额外的填充字节（ASCII '='）以确保如果输入的长度不是的倍数3，就是这种情况。

因此，如果解码引发“不正确的填充”错误然后删除任何空格并追加额外的ASCII'='使其长度为 3的倍数，然后再次尝试解码。（或者您可以重复添加一个垫字符并重试，最多3次。）

最简单的解决方案是确保您的数据包总是4个字节的倍数。

感谢您的解释。我发现了导致此错误的问题，并且它与电子邮件地址身份验证有关。 – duduklein

发布您的解决方案作为答案，并接受它来关闭此问题。 –

问题在于验证。 Django无法使用邮件服务器进行身份验证。一旦我解决了这个问题，问题就没有了。
