说明：

#mail.py使用方法：


1，本脚本同目录下文件介绍：
sender.list:邮件发送者邮箱和密码，第一行账号（如example@example.com）,第二行密码（必须项，不能为空）
receiver.list:邮件接收者列表，每行一个收件人(如example@example.com)
receivercc.list:邮件抄送者列表，每行一个收件人(如example@example.com)




调用方法举例1：
把发件人和收件人信息(sender.list和receiver.list)填好后，在mail.py所在目录执行
python mail.py  -s sender.list -r receiver.list






2,其它帮助信息获得方法：
在mail.py所在目录执行：python mail.py -h
显示：
Options:
  -h, --help            show this help message and exit
  -s SENDER, --sender=SENDER                                     //配置本脚本发件人信息存放的文件的路径  如 /tmp/tmp/list.list
                        file for sender of the mail
  -r RECEIVER, --receiver=RECEIVER                               //配置本脚本收件人列表存放的文件的路径  如 /tmp/tmp/list.list
                        list file for receivers of the mail
  -p CC, --cc=CC        list file for receivers of carbon copy   //配置抄送收件人列表存放的文件的路径  如 /tmp/tmp/list.list
  -t TITLE, --title=TITLE                                        //配置邮件的标题，字符串(不能有空格)
                        title of the email,string
  -c CONTENT, --content=CONTENT                                  //配置邮件的内容，文件路径（和-i冲突时，-i参数无效）
                        content of the mail,must be a file
  -a ATTACH, --attach=ATTACH                                     //配置邮件的附件，文件路径（有附件时，必须配置-n参数）
                        attachment of the file
  -n NAMEATTACH, --nameattach=NAMEATTACH                         //配置邮件的附件名称，字符串(不能有空格)（有附件时，必须配置本参数）
                        name for attachment of the file
  -l SERVER, --server=SERVER                                     //配置邮件的服务器，默认是smtp.163.com
                        log in to the server
  -i INFO, --info=INFO  information of the content,string,but not file //配置邮件的内容，字符串(不能有空格)（和-c冲突时，本参数无效）
  -f FORM, --form=FORM  form of the content,html or plain        //配置邮件的内容的类型，默认是plain
  
调用方法举例2：
在mail.py所在目录执行：
python mail.py  -s /root/tmp/sender.list -r /root/tmp/receiver.list -p /root/tmp/receivercc.list  -t test_the_py -c /root/tmp/content.log -a /root/tmp/attch.log -n attachname1.log 


将会把/root/tmp/content.log作为文件内容，
把/root/tmp/attch.log作为附件，
把attachname1.log作为附件名称，
把test_the_py作为邮件标题的邮件；
从/root/tmp/sender.list文件里的发件人，
发送到/root/tmp/receiver.list和/root/tmp/receivercc.list文件里的收件人列表。
