Python 发送 email 的两种方式

Python发送email的两种方式,分别为使用登录邮件服务器、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

二、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
