python发送附件的邮件

这里是代码，attachment函数不理解的，可以参考我的另一篇blog，http://blog.csdn.net/zmj_88888888/article/details/8725768

sendmail_mime.py

# -*- coding: utf8 -*-
import smtplib
from email import Utils,Encoders
import mimetypes,sys
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from email.mime.base import MIMEBase
#############
#要发给谁，这里发给2个人
#mailto_list=["[email protected]","[email protected]"]
#####################
#设置服务器，用户名、口令以及邮箱的后缀
mail_host="mail.xxxxx.com"
mail_user="[email protected]"
mail_pass="password"
mail_postfix="xxxxx.com"

#构造添加附件的函数attachment
def attachment(filename):
    fd = open(filename,'rb')
    mimetype,mimeencoding = mimetypes.guess_type(filename)
    if mimetype or (mimeencoding is None):
        mimetype = 'application/octet-stream'
    maintype,subtype = mimetype.split('/')
    if maintype == 'text':
        retval = MIMEText(fd.read(),_subtype=subtype)
    else:
        retval = MIMEBase(maintype,subtype)
        retval.set_payload(fd.read())
        Encoders.encode_base64(retval)
    retval.add_header('Content-Disposition','attachment',filename = filename)
    fd.close()
    return retval

def send_mail(to_list,sub,content):
    '''
    to_list:发给谁
    sub:主题
    content:内容
    send_mail("[email protected]","sub","content")
    '''
    me=mail_user
    msg = MIMEMultipart()
    msg['Subject'] = sub
    msg['From'] = me
    msg['To'] = to_list
    msg['Date'] = Utils.formatdate(localtime=1)
    msg['Message-ID'] = Utils.make_msgid()
    body = MIMEText(content)
    msg.attach(body)
    for filename in sys.argv[1:]:
        msg.attach(attachment(filename))
    try:
        s = smtplib.SMTP()
        s.connect(mail_host)
        s.login(mail_user,mail_pass)
        s.sendmail(me, to_list, msg.as_string())
        s.close()
        return True
    except Exception, e:
        print str(e)
        return False
if __name__ == '__main__':
    if send_mail("[email protected]","hello jason","do you know me!"):
        print "发送成功"
    else:
        print "发送失败"

python sendmail_mime.py mail.txt mail.txt.tar.gz 

这里发送了两个附件mail.txt和mail.txt.tar.gz

我自己写的，在windows上测试过，可以是用的，大家可以试试看，按照自己的需求来修改。
