1. 不带附件的 邮件：
#!/usr/bin/python# -*- coding: UTF-8 -*-import smtplibfrom email.mime.text import MIMETextfrom email.header import Headersender = 'zhoux.tian@xxx.com'receivers = ['zhoux.tian@xxx.com','zhoux.tian@xxx.com'] # 接收邮件，可设置为你的QQ邮箱或者其他邮箱# 三个参数：第一个为文本内容，第二个 plain 设置文本格式，第三个 utf-8 设置编码message = MIMEText('Python 邮件发送测试...', 'plain', 'utf-8')message['From'] = Header("菜鸟教程", 'utf-8') # 发送者message['To'] = Header("测试", 'utf-8') # 接收者#message['From'] = sender#message['To'] = ','.join(receivers)subject = 'Python SMTP 邮件测试'message['Subject'] = Header(subject, 'utf-8')try: smtpObj = smtplib.SMTP('smtp.xxx.com') smtpObj.sendmail(sender, receivers, message.as_string()) print "邮件发送成功"except smtplib.SMTPException: print "Error: 无法发送邮件" 2. 如果我们本机没有 sendmail 访问，也可以使用其他邮件服务商的 SMTP 访问（QQ、网易、Google等）：
#!/usr/bin/python# -*- coding: UTF-8 -*- import smtplibfrom email.mime.text import MIMETextfrom email.header import Header # 第三方 SMTP 服务mail_host="smtp.XXX.com" #设置服务器mail_user="XXXX" #用户名mail_pass="XXXXXX" #口令 sender = 'from@runoob.com'receivers = ['429240967@qq.com'] # 接收邮件，可设置为你的QQ邮箱或者其他邮箱 message = MIMEText('Python 邮件发送测试...', 'plain', 'utf-8')message['From'] = Header("菜鸟教程", 'utf-8')message['To'] = Header("测试", 'utf-8') subject = 'Python SMTP 邮件测试'message['Subject'] = Header(subject, 'utf-8') try: smtpObj = smtplib.SMTP() smtpObj.connect(mail_host, 25) # 25 为 SMTP 端口号 smtpObj.login(mail_user,mail_pass) smtpObj.sendmail(sender, receivers, message.as_string()) print "邮件发送成功"except smtplib.SMTPException: print "Error: 无法发送邮件" 3. 带附件：
#!/usr/bin/python# -*- coding: UTF-8 -*- import smtplibfrom email.mime.text import MIMETextfrom email.mime.multipart import MIMEMultipartfrom email.header import Header sender = 'from@runoob.com'receivers = ['429240967@qq.com'] # 接收邮件，可设置为你的QQ邮箱或者其他邮箱 #创建一个带附件的实例message = MIMEMultipart()message['From'] = Header("菜鸟教程", 'utf-8')message['To'] = Header("测试", 'utf-8')subject = 'Python SMTP 邮件测试'message['Subject'] = Header(subject, 'utf-8') #邮件正文内容message.attach(MIMEText('这是菜鸟教程Python 邮件发送测试……', 'plain', 'utf-8')) # 构造附件1，传送当前目录下的 test.txt 文件att1 = MIMEText(open('test.txt', 'rb').read(), 'base64', 'utf-8')att1["Content-Type"] = 'application/octet-stream'# 这里的filename可以任意写，写什么名字，邮件中显示什么名字att1["Content-Disposition"] = 'attachment; filename="test.txt"'message.attach(att1) # 构造附件2，传送当前目录下的 runoob.txt 文件att2 = MIMEText(open('runoob.txt', 'rb').read(), 'base64', 'utf-8')att2["Content-Type"] = 'application/octet-stream'att2["Content-Disposition"] = 'attachment; filename="runoob.txt"'message.attach(att2) try: smtpObj = smtplib.SMTP('localhost') smtpObj.sendmail(sender, receivers, message.as_string()) print "邮件发送成功"except smtplib.SMTPException: print "Error: 无法发送邮件"
