SMTP是发送邮件的协议，Python内置对SMTP的支持，可以发送纯文本邮件、HTML邮件以及带附件的邮件。
Python对SMTP支持有smtplib和email两个模块，email负责构造邮件，smtplib负责发送邮件。
注意：邮箱必须开启SMTP才可以通过该脚本发邮件
MIMEBase
|-- MIMENonMultipart
|-- MIMEApplication
|-- MIMEAudio
|-- MIMEImage
|-- MIMEMessage
|-- MIMEText
|-- MIMEMultipart
一般来说，不会用到MIMEBase，而是直接使用它的继承类。MIMEMultipart有attach方法，而MIMENonMultipart没有，只能被attach。
MIME有很多种类型，这个略麻烦，如果附件是图片格式，我要用MIMEImage，如果是音频，要用MIMEAudio，如果是word、excel，我都不知道该用哪种MIME类型了，得上google去查。
最懒的方法就是，不管什么类型的附件，都用MIMEApplication，MIMEApplication默认子类型是application/octet-stream。
