Python SMTP发送邮件

转载菜鸟教程

1. 不带附件的邮件：

#!/usr/bin/python
# -*- coding: UTF-8 -*-

import smtplib
from email.mime.text import MIMEText
from email.header import Header

sender = '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 smtplib
from email.mime.text import MIMEText
from 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 smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from 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"
