Python 傳送 email 的三種方式

Python傳送email的三種方式,分別為使用登入郵件伺服器、使用smtp服務、呼叫sendmail命令來發送三種方法

本文原文自米撲部落格:Python 傳送 email 的三種方式

Python傳送email比較簡單,可以通過登入郵件服務來發送,linux下也可以使用呼叫sendmail命令來發送,還可以使用本地或者是遠端的smtp服務來發送郵件,不管是單個,群發,還是抄送都比較容易實現。本米撲部落格先介紹幾個最簡單的傳送郵件方式記錄下,像html郵件,附件等也是支援的,需要時查文件即可。

 

一、登入郵件伺服器

通過smtp登入第三方smtp郵箱傳送郵件,支援 25 和 465埠

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 = '[email protected]'  
password = "mimvp-password"  
receiver = '[email protected]
' 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'

執行命令:

$ python python_email_1.py 
send success by port 25
send success by port 465

傳送結果,會收到兩封郵件,截圖其中一份郵件如下圖:

 

二、使用smtp服務

測試失敗,略過或留言指正

#!/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 = '[email protected]'  
password = "mimvp-password"  
receiver = '[email protected]'
  
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、呼叫sendmail命令

呼叫本機linux自身sendmail服務傳送郵件,不需要啟動sendmail後臺程序,不需要傳送者登入,郵件傳送者可以是任意名字,沒有限制。

特別注意:sendmail 命令傳送郵件,預設用25埠號,由於阿里雲、騰訊雲等封禁了25埠號,因此本示例需在開通25埠機器上測試

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 = '[email protected]'
recevier = '[email protected]'
subject = 'sendmail-subject'
html_content = 'hello mimvp.com'
send_mail(sender, recevier, subject, html_content)

執行命令:

python python_email_3.py

收件結果:
