Python3.3 邮件发送 含附件（各种类型文件）

1、廖雪峰教程代码会出现此种错误：
smtplib.SMTPServerDisconnected: please run connect() first，弃用

2、TypeError: getsockaddrarg: AF_INET6 address must be tuple, not str
服务器地址类型设定为元组
3、UnicodeEncodeError: 'utf-8’ codec can’t encode character '\udcc9’ in position 0: surrogates not allowed
有些采用读取附件内容然后再发送附件，读取附件中中文内容错误，utf-8 和 gbk均无效

可用程序代码：
