At our server one of our users sent an undeliverable mail with /bin/mail and with /usr/sbin/sendmail -q1m added a daemon. I was quite surprised when I saw in the mailog, that our server tried 2000 times within one day to reach the unknown host. I was also surprised a normal user can start sendmail as a daemon... I don't have time right now to look at that closer. I set the permissions of sendmail from rwsrwsr-x to rwxrwxr-x and changed the /var/spool/mqueue from rwxrwxrwx (as linuxconf creates it) to rwx-wx-wx. A normal user can yet still start a daemon, but sendmail doesn't process the mails in mqueue any more. Yet you can still use mail. Is sendmail supposed to work like that?
Assigning to a developer.This is an sendmail related issue and not a bugzilla related one so I am refiling it under product: Red Hat Linux and component: sendmail. Then the proper developer will be able to look at it.
This is normal behavior
