折腾:

【已解决】python中smtp用qq发送邮件出错:smtplib.SMTPAuthenticationError 530 Error A secure connection is required

期间,再去试试587,结果至少可以继续运行了:

结果:

    smtpObj.login(sender, senderPassword)

  File “/usr/local/Cellar/python/2.7.13/Frameworks/Python.framework/Versions/2.7/lib/python2.7/smtplib.py”, line 622, in login

    raise SMTPAuthenticationError(code, resp)

smtplib.SMTPAuthenticationError: (530, ‘Must issue a STARTTLS command first.’)

看到有:

s = smtplib.SMTP_SSL(“smtp.qq.com“, 465)

所以去搜:

python smtp SMTP ssl

果然是有单独的:

smtplib.SMTP_SSL

所以代码改为:

if useSSL:

    smtpObj = smtplib.SMTP_SSL(smtpServer, smtpPort)

else:

    smtpObj = smtplib.SMTP(smtpServer, smtpPort)

然后就发送成了,开了debug的smtp的log是:

【总结】

此处python中用smtp发送邮件,结果报错:

<code>smtplib.SMTPAuthenticationError: (530, 'Must issue a STARTTLS command first.')
</code>

的原因是:

QQ邮箱中用了SSL的465(或587)端口,结果smtp库调用是却是用的非SSL的函数:

<code>smtplib.SMTP(smtpServer, smtpPort)
</code>

换成:

<code>smtpObj = smtplib.SMTP_SSL(smtpServer, 465)
</code>

即可。
