详解Python发送email的三种方式_Python

Python 发送 email的三种方式，分别为使用登录邮件服务器、使用smtp服务、调用sendmail命令来发送三种方法

Python发送email比较简单，可以通过登录邮件服务来发送，linux下也可以使用调用sendmail命令来发送，还可以使用本地或者是远程的smtp服务来发送邮件，不管是单个，群发，还是抄送都比较容易实现。本米扑博客先介绍几个最简单的发送邮件方式记录下，像html邮件，附件等也是支持的，需要时查文档即可。

一、登录邮件服务器

通过smtp登录第三方smtp邮箱发送邮件，支持 25 和 465端口

vim python_email_1.py

									#!/usr/bin/env python

									# -*- coding:utf-8 -*-

									#

									# author: mimvp.com

									# 2015.10.05

									import smtplib 

									from email.mime.text import MIMEText 

									smtpHost = 'smtp.exmail.qq.com'

									sender = 'robot@mimvp.com'

									password = "mimvp-password"

									receiver = 'yanggang@mimvp.com'

									content = 'hello mimvp.com'

									msg = MIMEText(content) 

									msg['Subject'] = 'email-subject'

									msg['From'] = sender 

									msg['To'] = receiver 

									## smtp port 25

									smtpServer = smtplib.SMTP(smtpHost, 25)     # SMTP

									smtpServer.login(sender, password) 

									smtpServer.sendmail(sender, receiver, msg.as_string()) 

									smtpServer.quit() 

									print 'send success by port 25'

									## smtp ssl port 465

									smtpServer = smtplib.SMTP_SSL(smtpHost, 465)  # SMTP_SSL

									smtpServer.login(sender, password) 

									smtpServer.sendmail(sender, receiver, msg.as_string()) 

									smtpServer.quit() 

									print 'send success by port 465'

执行命令：

									$ python python_email_1.py 

									send success by port 25

									send success by port 465

发送结果，会收到两封邮件，截图其中一份邮件如下图：

二、使用smtp服务

测试失败，略过或留言指正

									#!/usr/bin/env python

									# -*- coding:utf-8 -*-

									#

									# author: mimvp.com

									# 2015.10.05

									import smtplib 

									from email.mime.text import MIMEText 

									import subprocess

									smtpHost = 'smtp.exmail.qq.com'

									sender = 'robot@mimvp.com'

									password = "mimvp-password"

									receiver = 'yanggang@mimvp.com'

									content = 'hello mimvp.com'

									msg = MIMEText(content)  

									if __name__ == "__main__":  

									  p = subprocess.Popen(['/usr/sbin/sendmail', '-t'], stdout=subprocess.PIPE) 

									  print(str(p.communicate()))

									  p_res = str(p.communicate()[0])

									  msg = MIMEText(p_res)

									  msg["From"] = sender 

									  msg["To"] = receiver 

									  msg["Subject"] = "hello mimvp.com"

									  s = smtplib.SMTP(smtpHost) 

									  s.login(sender, password)

									  s.sendmail(sender, receiver, msg.as_string()) 

									  s.quit() 

									  print 'send success'

三、调用sendmail命令

调用本机linux自身sendmail服务发送邮件，不需要启动sendmail后台进程，不需要发送者登录，邮件发送者可以是任意名字，没有限制。

特别注意：sendmail 命令发送邮件，默认用25端口号，由于阿里云、腾讯云等封禁了25端口号，因此本示例需在开通25端口机器上测试

vim python_email_3.py

									#!/usr/bin/env python

									# -*- coding:utf-8 -*-

									#

									# author: mimvp.com

									# 2015.10.05

									from email.mime.text import MIMEText

									from subprocess import Popen, PIPE

									import commands

									import sys 

									reload(sys)

									sys.setdefaultencoding('utf-8')

									def send_mail(sender, recevier, subject, html_content):

									    msg = MIMEText(html_content, 'html', 'utf-8')

									    msg["From"] = sender

									    msg["To"] = recevier

									    msg["Subject"] = subject

									    p = Popen(["/usr/sbin/sendmail", "-t"], stdin=PIPE)

									    p.communicate(msg.as_string())

									sender = 'robot@mimvp.com'

									recevier = 'yanggang@mimvp.com'

									subject = 'sendmail-subject'

									html_content = 'hello mimvp.com'

									send_mail(sender, recevier, subject, html_content)
