TimeoutError - Traceback（最后一次调用），Django-app - 发送电子邮件。 Python

Question

我正在尝试使用 'mailgun' 和 gmail 邮件从我的 Django 应用程序发送电子邮件，但每次我都收到错误。

在我的应用程序中，我有以下代码：

settings.py

EMAIL_HOST = 'smtp.mailgun.org'
EMAIL_PORT = 587
EMAIL_HOST_USER = 'aaa@mg.xxx.com'
EMAIL_HOST_PASSWORD = '#########'
EMAIL_USE_TLS = True

然后我运行命令行中的命令：

manage.py shell

[1] from django.core.mail import send_mail
[2] send_mail('subject', 'body of the message', 'aaa@mg.xxx.com', ['
recipient@aaa.com'])

我是用 gmail 还是用 'mailguna' 总是得到同样的错误

错误：

    718             err = None

TimeoutError: [WinError 10060]

我尝试更改设置 'TLS'、'mail port' 和 'SSL'，但它们总是以相同的错误结束。

当代码运行在应用程序外部时一切正常：

file_works_properly.py

import smtplib

from email.mime.text import MIMEText

msg = MIMEText('Title')  #Tresc wiadomosci
msg['Subject'] = "Hello world"
msg['From']    = "XXX@mg.bbb.com"
msg['To']      = "ccc@ccc.com"

s = smtplib.SMTP('smtp.mailgun.org', 587)

s.login('###@mg.bbb.com', '3###baa5e1f3###-26fa###0987')
s.sendmail(msg['From'], msg['To'], msg.as_string())
s.quit()

我们将不胜感激。

Answer 1

添加三个导入解决了我的问题（对于 'python manage.py shell' 或 views.py 文件）：

进口（在浏览量中。py/shell）：

from django.contrib import messages
from django.core.mail import send_mail
from django.conf import settings

其余活动不变：

settings.py

[...]
EMAIL_USE_TLS = True
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = 'myemail@gmail.com'
EMAIL_HOST_PASSWORD = 'mypassowrd'
EMAIL_PORT = 587

发送电子邮件（在浏览量中。py/shell）

send_mail(subject, message, from_email, [to_list_email])

(*对于 gmail.com 很重要) - 通常必须启用此 option。
