【Mail】自制的qmail用户空间检测脚本

本人使用qmail时间不长，发现vpopmail 的空间检测还不完善，一次给客户做项目，刚好有需求就写了这个脚本

结合Crontab使用效果还可以，有兴趣的网友可以试试，欢迎回馈顶贴！！

Sir/Madam:
         How are you!
   This e-mail was automatically sent from the mail.xxx.com.cn e-mail server.
   Your total mailbox size has exceeded 70% of the assigned quota ($QUOTA_K KB).It is $USED KB by now!
   If your mailbox fills,it becomes impossible to receive e-mail from other e-mail addresses.
   So that you can continue to receive e-mail,you need to remove some messages from your mailbox.
  
                                                             Your e-mail address: $ADDRESS
                                                                    Present size: $USED KB
                                                                    Quota   size: $QUOTA_K KB
