ipop3d[29470]: Mailbox vulnerable - directory /var/spool/mail must have 1777 protection

我将mail目录文件设为了600属性了，还是会出现1777 protection warning

感谢carelezz，请问1777中的1是什么属性呢，另外/var/spool/mail下的各个用户邮箱的权限应该设为怎样呢？

Best regards,

MailScanner[1091]: MailScanner child dying of old age

请问MailScanner child dying of old age应作何解？

1777的1表示sticky bit.

     A directory whose `sticky bit' is set becomes an append-only directory,
     or, more accurately, a directory in which the deletion of files is
     restricted.  A file in a sticky directory may only be removed or renamed
     by a user if the user has write permission for the directory and the user
     is the owner of the file, the owner of the directory, or the super-user.
     This feature is usefully applied to directories such as /tmp which must
     be publicly writable but should deny users the license to arbitrarily
     delete or rename each others' files.

表示mailscanner的子进程因为时间太长终止。

谢谢carelezz的热心回复,exchange里用exchange协议能够控制用户邮件保留多少天后自动删除，请问如何设置sendmail来保留邮件多少天后自动删除？


我觉得这个功能很实用，但一直找不到资料。

对不起，我不懂sendmail
只是对qmail有一点了解

能说说qmail 的优点吗.听说sendmail有很多不安全的方面，具体我也没去做研究。
