We are running a semi-private mail system with the following protection: d--x--x--x 2 root 1264 May 25 07:20 mail ./mail: total 342 -rw--w--w- 1 aaron 1172 May 22 17:28 aaron -rw--w--w- 1 alex 342 May 24 13:39 alex There are two intermitent problems associated with mail. One is that if two people simultaneously send mail to the same receipient the two message are intermingled in one mail message. For some reason the mail locking mechanism is not working. The other problem is that occasionally the file permissions are changed to -rw-r--r-- 1 alex 342 May 24 13:39 alex This occurs more frequently if the mail directory has permission d-wx-wx-wx 2 root 1264 May 25 07:20 mail I expect that there is a simpler way to have private mail and a more secure way also.
