一、参考文档：
1. RPi Email IP On Boot Debian http://elinux.org/RPi_Email_IP_On_Boot_Debian 2. How to convert list to string [duplicate] http://stackoverflow.com/questions/5618878/how-to-convert-list-to-string 3. Python for Loop Statements http://www.tutorialspoint.com/python/python_for_loop.htm 
二、cat bootSendEmail.py
#!/usr/bin/python

import subprocess
import smtplib
from email.mime.text import MIMEText
import datetime

# Change to your own account information
# Account Information
to            = '64128306@qq.com'            # Email to send to.
mail_user     = 'zengjf42@163.com'           # Email to send from.
mail_password = '填入授权密码'                           # Email password.
smtpserver    = smtplib.SMTP('smtp.163.com') # Server to use.

smtpserver.ehlo()                            # Says 'hello' to the server
smtpserver.starttls()                        # Start TLS encryption
smtpserver.ehlo()
smtpserver.login(mail_user, mail_password)   # Log in to server
today = datetime.date.today()                # Get current time/date

arg='ip route list'                          # Linux command to retrieve ip addresses.
# Runs 'arg' in a 'hidden terminal'.
p=subprocess.Popen(arg,shell=True,stdout=subprocess.PIPE)
data = p.communicate()                       # Get data from 'p terminal'.

# get ip data
ip_lines = data[0].splitlines()
ips = ""
for ip in ip_lines:
ips += ip + "\n"

# Creates the text, subject, 'from', and 'to' of the message.
msg = MIMEText(ips)
msg['Subject'] = 'IPs For RaspberryPi on %s' % today.strftime('%b %d %Y')
msg['From'] = "zengjf42@163.com"
msg['To'] = "64128306@qq.com"

# Sends the message
smtpserver.sendmail(mail_user, [to], msg.as_string())

# Closes the smtp server.
smtpserver.quit()

三、 将bootSendEmail.py放入/usr/bin/

四、modify /etc/rc.local
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

# Print the IP address
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
printf "My IP address is %s\n" "$_IP"
bootSendEmail.py                         # add this line
fi

exit 0

五、重启系统，并查看邮箱：

192.168.0.0/24 dev eth0  proto kernel  scope link  src 192.168.0.5
