#!/usr/bin/env python

# -*- coding:utf-8 -*-

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())

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())
