V23981-01.zip from https://edelivery.oracle.com which contains mysqlmonitoragent-22.214.171.1244-linux-glibc2.3-x86-64bit-installer.rpm
When I was testing the email alerting for my backup script I got an error:
/etc/mail/submit.cf: line 544: fileclass: cannot open '/etc/mail/trusted-users': Group writable directory
Luckily RPM was able to tell me that mysqlmonitoragent had set / to the wrong permissions.
# rpm -qf / filesystem-2.4.0-3.el5 mysqlmonitoragent-126.96.36.1994-0 # rpm -qvl mysqlmonitoragent-188.8.131.524-0 | head -1 drwxrwxr-x 2 root root 0 Nov 25 01:51 / # rpm -qvl filesystem-2.4.0-3.el5 | head -1 drwxr-xr-x 2 root root 0 Oct 1 2009 / # echo test | mail -s test firstname.lastname@example.org # /etc/mail/submit.cf: line 544: fileclass: cannot open '/etc/mail/trusted-users': Group writable directory
I've filed Bug #60752 for this. So watch out for this bug if you're using mysqlmonitoragent RPM's!
The work-around is to do a "chmod 755 /".
