Python發送email的三種方式，分別為使用登錄郵件服務器、使用smtp服務、調用sendmail命令來發送三種方法

本文原文自米撲博客：Python 發送 email 的三種方式

Python發送email比較簡單，可以通過登錄郵件服務來發送，linux下也可以使用調用sendmail命令來發送，還可以使用本地或者是遠程的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。本米撲博客先介紹幾個最簡單的發送郵件方式記錄下，像html郵件，附件等也是支持的，需要時查文檔即可。

一、登錄郵件服務器

通過smtp登錄第三方smtp郵箱發送郵件，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 = '[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

發送結果，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、調用sendmail命令

調用本機linux自身sendmail服務發送郵件，不需要啟動sendmail後臺進程，不需要發送者登錄，郵件發送者可以是任意名字，沒有限制。

特別注意：sendmail 命令發送郵件，默認用25端口號，由於阿里雲、騰訊雲等封禁了25端口號，因此本示例需在開通25端口機器上測試

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)
