Python發送email的三種方式，分別爲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
原文請參見米撲博客：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，羣發，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

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

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，不需要啓動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

執行命令：
python python_email_3.py
收件結果：
![]()
