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。
