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
20.12. smtplib — SMTP protocol client — Python 2.7.14 documentation

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。
