Python发送email还是比较简单的，可以通过登录邮件服务来发送，linux下也可以使用调用sendmail命令来发送，还可以使用本地或者是远程的smtp服务来发送邮件，不管是单个，群发，还是抄送都比较容易实现。

先把几个最简单的发送邮件方式记录下，像html邮件，附件等也是支持的，需要时查文档即可

1 登录邮件服务

#!/usr/bin/env python
# -*- coding: utf-8 -*-
#python2.7x
#send_simple_email_by_account.py @2014-07-30
#author: orangleliu

'''
使用python写邮件 simple
使用126 的邮箱服务
'''

import smtplib
from email.mime.text import MIMEText

SMTPserver = 'smtp.126.com'
sender = 'liuzhizhi123@126.com'
password = "xxxx"

message = 'I send a message by Python. 你好'
msg = MIMEText(message)

msg['Subject'] = 'Test Email by Python'
msg['From'] = sender
msg['To'] = destination

mailserver = smtplib.SMTP(SMTPserver, 25)
mailserver.login(sender, password)
mailserver.sendmail(sender, [sender], msg.as_string())
mailserver.quit()
print 'send email success'

2调用sendmail命令 （Linux）

# -*- coding: utf-8 -*-
#python2.7x
#send_email_by_.py
#author: orangleliu
#date: 2014-08-15
'''
用的是sendmail命令的方式

这个时候邮件还不定可以发出来，hostname配置可能需要更改
'''

from email.mime.text import MIMEText
from subprocess import Popen, PIPE

def get_sh_res():
p = Popen(['/Application/2.0/nirvana/logs/log.sh'], stdout=PIPE)
return str(p.communicate()[0])

def mail_send(sender, recevier):
print "get email info..."
msg = MIMEText(get_sh_res())
msg["From"] = sender
msg["To"] = recevier
msg["Subject"] = "Yestoday interface log results"
p = Popen(["/usr/sbin/sendmail", "-t"], stdin=PIPE)
res = p.communicate(msg.as_string())
print 'mail sended ...'

if __name__ == "__main__":
s = "957748332@qq.com"
r = "zhizhi.liu@chinacache.com"
mail_send(s, r)

3 使用smtp服务来发送（本地或者是远程服务器)

#!/usr/bin/env python
# -*- coding: utf-8 -*-
#python2.7x
#send_email_by_smtp.py
#author: orangleliu
#date: 2014-08-15
'''
linux 下使用本地的smtp服务来发送邮件
前提要开启smtp服务，检查的方法
#ps -ef|grep sendmail
#telnet localhost 25

这个时候邮件还不定可以发出来，hostname配置可能需要更改
'''
import smtplib
from email.mime.text import MIMEText
from subprocess import Popen, PIPE

def get_sh_res():
p = Popen(['/Application/2.0/nirvana/logs/log.sh'], stdout=PIPE)
return str(p.communicate()[0])

def mail_send(sender, recevier):
msg = MIMEText(get_sh_res())
msg["From"] = sender
msg["To"] = recevier
msg["Subject"] = "Yestoday interface log results"
s = smtplib.SMTP('localhost')
s.sendmail(sender, [recevier], msg.as_string())
s.quit()
print 'send mail finished...'

if __name__ == "__main__":
s = "zhizhi.liu@chinacache.com"
r = s
mail_send(s, r)
