Python 發送 email 的三種方式

Python發送email的三種方式，分別爲使用登陸郵件服務器、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，能夠經過登陸郵件服務來發送，linux下也能夠使用調用sendmail命令來發送，還能夠使用本地或者是遠程的smtp服務來發送郵件，無論是單個，羣發，仍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，須要時查文檔便可。

1、登陸郵件服務器

經過smtp登陸第三方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 = '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'

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，截圖其中一份郵件以下圖：

2、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 = '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'

3、調用sendmail命令

調用本機linux自身sendmail服務發送郵件，不須要啓動sendmail後臺進程，不須要發送者登陸，郵件發送者能夠是任意名字，沒有限制。

特別注意：sendmail 命令發送郵件，默認用25端口號，因爲阿里雲、騰訊雲等封禁了25端口號，所以本示例需在開通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 = 'robot@mimvp.com'
recevier = 'yanggang@mimvp.com'
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：
