Python邮件群发，做广告用的，注意中文编码

昨天用Python写了个邮件群发工具，做广告用的，注意中文编码，代码如下：

# -*- coding: cp936 -*-   
  
import email

import random
import time
import string
from email.MIMEMultipart import MIMEMultipart   
from email.MIMEText import MIMEText

def sendEmail(authInfo, fromAdd, toAdd, subject, plainText, htmlText):   
  
        strFrom = fromAdd   
        strTo = toAdd   
  
        server = authInfo.get('server')   
        user = authInfo.get('user')   
        passwd = authInfo.get('password')   
  
        if not (server and user and passwd) :   
                print 'incomplete login info, exit now'  
                return  
  
        # 设定root信息   
        msgRoot = MIMEMultipart('related')   
        msgRoot['Subject'] = subject   
        msgRoot['From'] = strFrom   
        msgRoot['To'] = strTo   
        msgRoot.preamble = 'This is a multi-part message in MIME format.'  
  
        # Encapsulate the plain and HTML versions of the message body in an   
        # 'alternative' part, so message agents can decide which they want to display.   
        msgAlternative = MIMEMultipart('alternative')   
        msgRoot.attach(msgAlternative)   
  
        #设定纯文本信息   
#        msgText = MIMEText(plainText, 'plain', 'gb2312')   
#        msgAlternative.attach(msgText)

        msgText = MIMEText(htmlText, 'html', 'gb2312')

#        msgRoot.attach(msgImage)   
  
       #发送邮件   
        smtp = smtplib.SMTP()   
       #设定调试级别，依情况而定   
        smtp.set_debuglevel(1)   
        smtp.connect(server)   
        smtp.login(user, passwd)
        smtp.sendmail(strFrom, strTo, msgRoot.as_string())   
#        smtp.sendmail(strFrom, strTo, msgRoot.as_string())   
        smtp.quit()
