使用yahoo的imaplib时，出现凭证错误。

Question

我有下面的代码，我正在jupyter笔记本中运行。 我试图登录到yahoo电子邮件帐户，并从一个文件夹中下载所有的电子邮件。 当我尝试运行代码时，我得到了下面的错误。 当我只是去yahoo.com用相同的电子邮件地址和密码登录时，它可以正常工作。 有人知道问题出在哪里吗？ 下面的邮件是一个假的例子）。

代码来自github repo。https:/gist.github.comrobulouski7442321。

代码：

import imaplib, email, getpass
import sys
from email.utils import getaddresses


IMAP_SERVER = 'imap.mail.yahoo.com'
EMAIL_ACCOUNT = '[email protected]'
EMAIL_FOLDER = 'TheFolder'
OUTPUT_DIRECTORY = '/Users/name/Desktop/Stuff/NewFolder'


PASSWORD = getpass.getpass()


def process_mailbox(M):
    """
    Dump all emails in the folder to files in output directory.
    """

    rv, data = M.search(None, "ALL")
    if rv != 'OK':
        print("No messages found!")
        return

    for num in data[0].split():
        rv, data = M.fetch(num, '(RFC822)')
        if rv != 'OK':
            print("ERROR getting message", num)
            return
        print("Writing message ", num)
        f = open('%s/%s.eml' %(OUTPUT_DIRECTORY, num), 'wb')
        f.write(data[0][1])
        f.close()

def main():
    M = imaplib.IMAP4_SSL(IMAP_SERVER)
    M.login(EMAIL_ACCOUNT, PASSWORD)
    rv, data = M.select(EMAIL_FOLDER)
    if rv == 'OK':
        print("Processing mailbox: ", EMAIL_FOLDER)
        process_mailbox(M)
        M.close()
    else:
        print("ERROR: Unable to open mailbox ", rv)
    M.logout()


if __name__ == "__main__":
    main()

错误：

更新。

我进入我的雅虎账户安全设置，并更新 "允许使用不太安全的登录的应用程序"，允许。 现在，当我在jupyter笔记本中运行代码时，我得到了下面的错误信息。

错误。

你有没有用雅虎邮件来解决这个问题？我有类似这样的代码，可以用gmail，但不能让它与雅虎工作。
