Question

我正在尝试使用这种方法（请参阅下文）来验证电子邮件地址，这种方法在无数不同的地方以一种或另一种形式被引用和推荐。问题是当我进入“ server.connect（mxRecord）”部分时，它停顿并超时了100％。

我尝试过：

至少30个不同的域名，以确保这不是特定于某个域的一些网络问题
调整超时限制
明确指定要连接的端口（465＆587）
运行“ smtplib.SMTP_SSL（）”而不是“ smtplib.SMTP（）”

我的设置：

家庭wifi
没有代理人

import dns.resolver
import smtplib
import socket

addressToVerify = 'rickymartin@yahoo.com'
domainToVerify = 'yahoo.com'

records = dns.resolver.query(domainToVerify, 'MX')
mxRecord = records[0].exchange
mxRecord = str(mxRecord)
print(mxRecord)

server = smtplib.SMTP(timeout=20)
server.set_debuglevel(0)
server.connect(mxRecord)
server.helo(server.local_hostname)
server.mail('me@domain.com')
code, message = server.rcpt(str(addressToVerify))
server.quit()

if code == 250:
    print('Valid')
else:
    print('Invalid')

这是我收到的错误：


Traceback (most recent call last):
  File "email-validator.py", line 17, in <module>
    server.connect(mxRecord)
  File "/usr/local/Cellar/python/3.7.1/Frameworks/Python.framework/Versions/3.7/lib/python3.7/smtplib.py", line 336, in connect

smtplib connect（）调用总是超时
