The remedy that Nolan provided corrected the use for non-root users (for a time). HOWEVER, sendmail's privileges revert back over time and the owner becomes mail again and I don't know when. I even rebooted my machine to see if the privledges changed after reboot. They didn't as far as I could see. So, over a period of time ... I went to lunch and behold -r-s, reverts to -r-x. How does this happen?

[root@sharkbait bin]# ls -alt sendmail -r-s--x--x 1 root mail 72372 Nov 23 11:12 sendmail* [root@sharkbait bin]# ls -alt sendmail -r-s--x--x 1 root mail 72372 Nov 23 11:12 sendmail* [root@sharkbait bin]# ls -alt sendmail -r-s--x--x 1 root mail 72372 Nov 23 11:12 sendmail* [root@sharkbait bin]# ls -alt sendmail -r-x--x--x 1 root mail 72372 Nov 23 11:12 sendmail* [root@sharkbait bin]# chmod 4511 sendmail [root@sharkbait bin]# ls -alt sendmail -r-s--x--x 1 root mail 72372 Nov 23 11:12 sendmail* [root@sharkbait bin]#
