Question

我正在尝试使用python smtplib模块发送邮件，但是我收到了错误。

import smtplib
s = smtplib.SMTP('smtp.gmail.com', 587)
s.ehlo()
s.starttls()
s.login("xxxxxxxx@gmail.com", "yyyyyyy")
message = "Message_you_need_to_send"
s.sendmail("xxxxxxxxx@gmail.com", "aaaaaaaaa@gmail.com", message)
s.quit()

我收到如下错误：

追踪（最近一次调用最后一次）：文件＆＃34; /home/engineer/demo.py"，第52行 s.starttls（）File＆＃34; /usr/lib/python2.7/smtplib.py" ;,第637行，在starttls中提出SMTPException（＆＃34;服务器不支持STARTTLS扩展名。＆＃34;）SMTPException：服务器不支持STARTTLS扩展名。

我从另一个链接中引用解决方案。您可以尝试在s.starttls()之前删除s.set_debuglevel(1)。

我使用自己的gmail帐户测试了您的代码，似乎代码应该与s.echlo（）一起使用。您可以查看您的Gmail安全设置，例如启用安全性较低的应用，Let less secure apps use your account

您还可以使用import smtplib

启用调试

s = smtplib.SMTP('smtp.gmail.com', 587)

s.set_debuglevel(1)

s.ehlo()

s.starttls()

就代码而言，没有任何变化，最终发现，问题与足够的防火墙权限相关联。
