fromaddr = 'XXX@XX.com'
toaddrs  = 'XXX@XX.com    '

server = smtplib.SMTP('smtp.gmail.com:587')
server.ehlo()
server.starttls()
server.login(username,password)
server.sendmail(fromaddr, toaddrs, msg)
server.quit()

error msg:socket.error: [Errno 10061] 由于目标机器主动拒绝，无法建立连接

Answer 1

如 Cid-EL 所述， You have to enable less secure apps in GMAIL settings

但是，打开该特定选项并不安全。

Gmail 提供 API 来执行邮件操作。 GMAIL API 支持多种语言。

对于 Python API:Python with Gmail

对于 Java API:Java with Gmail

稍加努力，但您可以获得安全连接!!

第 1 步:开启 GMAIL API

第 2 步:安装 Google 客户端库

pip install --upgrade google-api-python-client

第 3 步:使用 GMAIL API 发送邮件的代码示例
