1.linux服务器发送邮件，许多人会直接用mail命令发送，虽然可以发送成功，但是许多都会被互联网邮箱当初垃圾邮件处理

2.mutt和msmtp相关于linux下的邮件客户端，和windows上的outlook,foxmail之类有点类似

3.安装mutt和msmtp虽然可以，但是通过python脚本也可以代替，如下

ubuntu@ubuntu:/etc/nagios3/scripts$ cat sendmail

#!/usr/bin/python

import smtplib

import string

import sys

import getopt

def usage():

  print """sendmail is a send mail Plugins

  Usage:

  sendmail [-h|--help][-t|--to][-s|--subject][-m|--message]

  Options:

         --help|-h)

                print sendmail help.

         --to|-t)

                Sets sendmail to email.

         --subject|-s)

                 Sets the mail subject.

         --message|-m)

                 Sets the mail body

   Example:

          only one to email  user

         ./sendmail -t 'eric@nginxs.com' -s 'hello eric' -m 'hello eric,this is sendmail test!

          many to email  user

         ./sendmail -t 'eric@nginxs.com,yangzi@nginxs.com,zhangsan@nginxs.com' -s 'hello eric' -m 'hello eric,this is sendmail test!"""

  sys.exit(3)

try:

  options,args = getopt.getopt(sys.argv[1:],"ht:s:m:","--help --to= --subject= --message=")

except getopt.GetoptError:

  usage()

for name,value in options:

   if name in ("-h","--help"):

      usage()

   if name in ("-t","--to"):

# accept message user

      TO = value

      TO = TO.split(",")

   if name in ("-s","--title"):

      SUBJECT = value

   if name in ("-m","--message"):

      MESSAGE = value

      MESSAGE = MESSAGE.split('\\n')

      MESSAGE = '\n'.join(MESSAGE)

#smtp HOST

HOST = "smtp.126.com"      （这个是126的smtp服务域名）        

#smtp port

PORT = "25"                 （126邮箱smtp端口号）            

#FROM mail user

USER = 'Czar_test'      （你注册126邮箱的用户名）                  

#FROM mail password

PASSWD = 'test123'       （你注册126邮箱的密码）            

#FROM EMAIL

FROM = "Czar_test@126.com"   （你的126邮箱地址）

try:

  BODY = string.join((

     "From: %s" % FROM,

     "To: %s" % TO,

     "Subject: %s" % SUBJECT,

     "",

     MESSAGE),"\r\n")

  smtp = smtplib.SMTP()

  smtp.connect(HOST,PORT)

  smtp.login(USER,PASSWD)

  smtp.sendmail(FROM,TO,BODY)

  smtp.quit()

except:

  print "UNKNOWN ERROR"

  print "please look help"

  print "./sendmail -h"

然后测试发送邮件

ubuntu@ubuntu:/etc/nagios3/scripts$ /etc/nagios3/scripts/sendmail -t "yongkang_tian@126.com" -s "Nagios Test" -m "Hello Wrold"

二.nagios命令文件里面添加代码

ubuntu@ubuntu:/etc/nagios3$ vim commands.cfg

define command{

       command_name    notify-host-by-email

       command_line    /etc/nagios3/scripts/sendmail  -t $CONTACTEMAIL$ -s "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" -m "%b" -m "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n"

       }

define command{

       command_name    notify-service-by-email

       command_line    /etc/nagios3/scripts/sendmail -t $CONTACTEMAIL$ -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" -m "%b" -m "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$\n"

       }
