详解Python发送email的三种方式

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)

执行命令：

python python_email_3.py
