python - Django- [Errno 111]使用smtp时连接被拒绝

我正在开发一个Django应用程序，它具有向用户发送电子邮件的功能。在一个测试案例中，我有一个联系人表单，它通过gmail使用smtp将表单数据作为电子邮件的一部分提交。我禁用了captchas，因为我在this video playlist 中被告知我一直在学习教程，但是当我单击submit按钮时，由于某种原因我得到了[Errno 111]。在看到this和another SO post之后，我了解到我需要在实时服务器（而不仅仅是本地主机）上运行站点才能发送电子邮件。但是，当我在服务器上尝试时，我得到了与以前相同的错误。我很确定我遵循了所有正确的步骤，那么问题出在哪里呢？
以下是错误回溯：

views.py文件中的联系人表单

from django.shortcuts import render
from django.conf import settings
from .forms import ContactForm, SignUpForm
# Create your views here.

from django.core.mail import send_mail

def contact(request):
    form = ContactForm(request.POST or None)
    if form.is_valid():
        # for key, value in form.cleaned_data.iteritems():
        #   print key, value
        form_email = form.cleaned_data.get("email")
        form_message = form.cleaned_data.get("message")
        form_full_name = form.cleaned_data.get("full_name")
        # print form.cleaned_data
        subject = "Site contact form"
        from_email = settings.EMAIL_HOST_USER
        to_email = [from_email, '[e-mail]']
        contact_message = '''
        %s: %s via %s
        '''%(form_full_name, form_message, form_email)
        send_mail(subject, contact_message, from_email, [to_email], fail_silently = True )

    context = {
        "form": form
    }
    return render(request, "forms.html", context)

最佳答案

在你的密码里；

to_email = [from_email, '[e-mail]']

是一个列表，然后再次传递给列表中的电子邮件参数。
改变这一点；

send_mail(subject, contact_message, from_email, [to_email], fail_silently = True )

到

send_mail(subject, contact_message, from_email, to_email, fail_silently = True )
