Question

我在Django

发送邮件时遇到问题

我按照以下链接设置了我的Gmail：

https://support.google.com/mail/answer/7126229?visit_id=1-636278779262945155-948643181&rd=1#cantsignin

我在线尝试了所有解决方案，但仍然得到[Errno -2]

我发现有人说这是因为DNS问题，有人可以告诉我我的代码有什么问题吗？有没有解决方案？

views.py

import django
from django import settings
from django.core.mail import send_mail

def contact(request):
    send_mail('subject','message',settings.EMAIL_HOST_USER,['zwt467875460@gmail.com'],fail_silently = False)
    return HttpResponseRedirect('/contact/thanks')
def thanks(request): 
    return HttpResponse('thanks!')

settings.py

#email config
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gamil.com'
EMAIL_PORT = 587
EMAIL_HOST_USER='zwt467875460@gmail.com'
EMAIL_HOST_PASSWORD='*********'        #my gmail password
EMAIL_USER_TLS = True
DEFAULT_FORM_EMAIL = EMAIL_HOST_USER
ACCOUNT_EMAIL_VERIFICATION = 'none'

gaierror: [Errno -2] Name or service not known

并在Django错误页面中：

Exception Location:     /usr/lib/python2.7/socket.py in create_connection, line 557

我想我的问题是Gmail认为我没有固定或正确的DNS 所以我不能创建一个套接字

然后我尝试了sendmail：安装sendmail，sendmail-cf并配置后，

我试过了：

 echo "Subject: sendmail test" | sendmail -v zwt467875460@gmail.com

，输出是（我省略了发送细节）：

354 Enter mail, end with "." on a line by itself
>>> .

连接被smtp.gmail.com

拒绝

检查您的Gmail帐户设置是否启用了IMAP / POP。同时检查是否启用了对“安全性较低的应用”的访问权限。如果没有，请点击链接：https://support.google.com/accounts/answer/6010255
