本文以实例形式展示了python发送email功能的实现方法，有不错的实用价值的技巧，且功能较为完善。具体实现方法如下：

主要功能代码如下：

#/usr/bin/env python
# -*- encoding=utf-8 -*-

import base64
import smtplib
from email.mime.multipart import mimemultipart
from email.mime.text import mimetext

class ccsendmail:
  def __init__(self,host="your.mailhost.com",username='fromuser@xxx.com',password='passwd'):
    self.__smtp=smtplib.smtp(host)
    self.__subject=none
    self.__content=none
    self.__from=none
    self.__to=[]
    self.__style='html'
    self.__charset='gb2312'
    self.username = username
    self.password = password
    self.fromalias='fromuser' #发件人别名
    self.from2=''
    
  def close(self):
    try:
      self.__smtp.quit()
    except exception ,e:
      pass  
  def setfromalias(self,alias):
    self.fromalias=alias
  def setstyle(self,style):
    self.__style = style
  def setfrom2(self,from2):
    self.from2=from2
    
  def setsubject(self,subject):
    self.__subject=subject
    
  def setcontent(self,content):
    self.__content=content
    
  def setfrom(self,address):
    self.__from=address
    
  def addto(self,address):
    self.__to.append(address)
    
  def setcharset(self,charset):
    self.__charset=charset
    
  def send(self):
    try:
      self.__smtp.set_debuglevel(1)
      
      #login if necessary
      if self.username and self.password:
        self.__smtp.login(self.username,self.password)
        
      msgroot = mimemultipart('related')
      msgroot['subject'] = self.__subject
      aliasb6=base64.encodestring(self.fromalias.encode(self.__charset))
      if len(self.from2)==0:
        msgroot['from'] = "=?%s?b?%s?=%s"%(self.__charset,aliasb6.strip(),self.__from)
      else:
        msgroot['from'] = "%s"%(self.from2)
      msgroot['to'] = ";".join(self.__to)
      
      msgalternative = mimemultipart('alternative')
      msgroot.attach(msgalternative)
      
      msgtext = mimetext(self.__content, self.__style,self.__charset)
      msgalternative.attach(msgtext)

      self.__smtp.sendmail(self.__from,self.__to,msgroot.as_string())
      return true
    except exception,e:
      print "error ",e
      return false
    
  def clearrecipient(self):
    self.__to = []
  
  #给单个人发送邮件
  def sendhtml(self,address,title,content):
    self.setstyle('html')
    self.setfrom("<%s>"%self.username)
    if not isinstance(content,str):
      content = content.encode('gb18030')
    self.addto(address)
    self.setsubject(title)
    self.setcontent(content)
    ret = self.send()
    self.close()
    return ret
  
  #群发邮件
  def sendmorehtml(self,addresslist,title,content):
    self.setstyle('html')
    self.setfrom("<%s>"%self.username)
    if not isinstance(content,str):
      content = content.encode('gb18030')
    for address in addresslist:
      self.addto(address)
    self.setsubject(title)
    self.setcontent(content)
    ret = self.send()
    self.close()
    return ret

#测试
def main():
  send=ccsendmail()
  send.sendhtml('touser@xxx.com',u'邮件标题',u'邮件内容')
  #send.sendmorehtml([touser1@xx.com,touser2@xx.com],u'邮件标题',u'邮件内容')
 
if __name__=='__main__':
  main()
