Question

import smtplib

host = 'smtp.gmail.com'
port = 587
username = 'rajinirajadev@gmail.com'
password = '*************'
from_email = username
to_list = ['rajiniraja00@gmail.com']

email_conn = smtplib.SMTP(host,port)
email_conn.ehlo()
email_conn.starttls()
email_conn.login(username, password)
email_conn.sendmail(from_email, to_list, 'that is send via smtplib')
email_conn.quit()

这是我得到的错误。我关闭了两步验证并启用了允许gmail上的安全应用。

Answer 1

当我使用我的gmail帐户发送电子邮件时，我发生了同样的问题。即通过host ='smtp.gmail.com'

但是当我使用Outlook帐户（即，通过host ='smtp.outlook.com'）时，此问题已解决，并且收到的消息为“（（235，b'2.7.0身份验证成功”））

结论-Gmail垃圾邮件安全性被阻止，因为该脚本将该脚本视为某些不受信任的来源，并向我各自的帐户发送了一封邮件，该邮件已阻止登录免税
