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：

#!/usr/bin/python
    # -*- coding: UTF-8 -*-
    import smtplib
    import email.mime.multipart
    import email.mime.text
    from email.mime.text import MIMEText
    from email.mime.multipart import MIMEMultipart
    from email.mime.application import MIMEApplication
    
    def send_email(smtpHost, sendAddr, password, recipientAddrs, subject='', content=''):
        msg = email.mime.multipart.MIMEMultipart()
        msg['from'] = sendAddr
        msg['to'] = recipientAddrs
        msg['subject'] = subject
        content = content
        txt = email.mime.text.MIMEText(content, 'plain', 'utf-8')
        msg.attach(txt)
    
    
        # 添加附件，传送D:/软件/yasuo.rar文件
        part = MIMEApplication(open('D:/软件/yasuo.rar','rb').read())
        part.add_header('Content-Disposition', 'attachment', filename="yasuo.rar")
        msg.attach(part)
    
        smtp = smtplib.SMTP()
        smtp.connect(smtpHost, '25')
        smtp.login(sendAddr, password)
        smtp.sendmail(sendAddr, recipientAddrs, str(msg))
        print("发送成功！")
        smtp.quit()
    
    try:
        subject = 'Python 测试邮件'
        content = '这是一封来自 Python 编写的测试邮件。'
        send_email('xxsmtp.xxx.com.cn', 'fish@xxx.com.cn', '123456', 'fish@xxx.com.cn', subject, content)
    except Exception as err:
        print(err)
