Question

呃，我尝试过很多方法，到目前为止我能在网上找到，但无济于事。我的主要目标是从私有LAN上的基于Django的Web应用程序发送电子邮件。我不在乎它是怎么发生的...... smtp或win32com和outlook ......任何东西，只要它有效。

在django shell中使用django默认设置和此代码：

from django.core.mail import send_mail
send_mail('subject','message','myemail@email.com',['myemail@email.com'])

我收到此错误：

Traceback (most recent call last):
    File "<console>", line 1, in <module>
    File "C:\Python27_32\lib\site-packages\django\core\mail\__init__.py", line 50, in send_mail
        connection=connection).send()
    File "C:\Python27_32\lib\site-packages\django\core\mail\message.py", line 274, in send
        return self.get_connection(fail_silently).send_messages([self])
    File "C:\Python27_32\lib\site-packages\django\core\mail\backends\smtp.py", line 87, in send_messages
        new_conn_created = self.open()
    File "C:\Python27_32\lib\site-packages\django\core\mail\backends\smtp.py", line 48, in open
        local_hostname=DNS_NAME.get_fqdn())
    File "C:\Python27_32\lib\smtplib.py", line 250, in __init__
        (code, msg) = self.connect(host, port)
    File "C:\Python27_32\lib\smtplib.py", line 311, in connect
        (code, msg) = self.getreply()
    File "C:\Python27_32\lib\smtplib.py", line 359, in getreply
        + str(e))
SMTPServerDisconected: Connection unexpectedly closed: [Errno 10057] A request to send or 
receive data was disallowed because the socket is not connected and (when sending on a 
datagram socket using a sendto call) no address was supplied

在深入研究代码后，我在smtplib中插入了一个print语句，显示地址为('localhost', 25)。所以我不知道它为什么说没有提供地址。那时我发现django-smtp-ssl.py并在安装后将以下内容添加到我的设置中：

EMAIL_USE_TLS = True #also tried 1
EMAIL_BACKEND = 'django_smtp_ssl.SSLEmailBackend'
EMAIL_HOST = 'localhost'
EMAIL_HOST_USER = 'myemail@email.com'
EMAIL_HOST_PASSWORD = 'mypassword'
EMAIL_PORT = 465

然后执行相同的代码，我现在得到：

Traceback (most recent call last):
    File "<console>", line 1, in <module>
    File "C:\Python27_32\lib\site-packages\django\core\mail\__init__.py", line 50, in send_mail
        connection=connection).send()
    File "C:\Python27_32\lib\site-packages\django\core\mail\message.py", line 274, in send
        return self.get_connection(fail_silently).send_messages([self])
    File "C:\Python27_32\lib\site-packages\django\core\mail\backends\smtp.py", line 87, in send_messages
        new_conn_created = self.open()
    File "C:\Python27_32\lib\site-packages\django_smtp_ssl.py", line 12, in open
        local_hostname=DNS_NAME.getfqdn())
    File "C:\Python27_32\lib\smtplib.py", line 777, in __init__
        SMTP.__init__(self, host, port, local_hostname, timeout)
    File "C:\Python27_32\lib\smtplib.py", line 250, in __init__
        (code, msg) = self.connect(host, port)
    File "C:\Python27_32\lib\smtplib.py", line 311, in connect
        (code, msg) = self.getreply()
    File "C:\Python27_32\lib\smtplib.py", line 355, in getreply
        line = self.file.readline()
    File "C:\Python27_32\lib\smtplib.py", line 186, in readline
        chr = self.sslobj.read(1)
    File "C:\Python27_32\lib\ssl.py", line 160, in read
        return self._sslobj.read(len)
AttributeError: 'NoneType' object has no attribute 'read'

我还尝试使用Apache在生产环境中通过Outlook和win32com发送邮件。我在尝试此操作时收到了几个不同的例外情况，例如：'Server execution failed和'Call was rejected by callee'。虽然它适用于django shell（当然）。

有没有人看到这些错误并找到解决方案？谢谢你的帮助！

它的解决方法，简直就是粗制滥造，但它会完成工作，直到有更好的解决方案出现。

首先我创建了一个custom command，可以从manage.py调用，因为它不是从Apache服务器执行的（这进一步告诉我系统不会将Apache识别为自动电子邮件的有效用户一代，当然有一种告诉系统的方式＆＃34;它没问题＆＃34;）。

之后，我在Windows任务计划程序中创建了一个每30分钟运行一次的任务（这足以达到目标）。动作：

Start a program  C:\python27_32\python.exe C:\www\myproject\manage.py send_email

MyApp的/管理/命令/ send_email.py

from django.core.management.base import BaseCommand
from myapp.util.gen_email import AutoEmail #custom code to generate email via win32com
from myapp.models import MyModel

class Command(BaseCommand):
    def __init__(self, *args, **kwargs):
        super(Command, self).__init__(*args, **kwargs)
        items = MyModel.objects.filter(status__in=['status_a','status_b'])
        if items:
            self.send_proc_email()

    def send_proc_email(self):
        subject = 'There are new items to process'
        to = 'someemail@email.com'
        message = ''
        email = AutoEmail(subject, message, to)

    def handle(self, *args, **kwargs):
        pass

我知道，这远非最佳，但如果有效的话，嘿......
