Are these settings correct?

[Hongwei Li]

While I am checking the posible reason that the php mail() does not work
in my fc3 system, I found the following settings:

# ls -lZ /usr/sbin/send*
lrwxrwxrwx  root     root     user_u:object_r:sbin_t
/usr/sbin/sendmail -> /etc/alternatives/mta
-rwxr-sr-x  root     smmsp    system_u:object_r:sbin_t
/usr/sbin/sendmail.sendmail

and all files in /etc/alternatives/ show either user_u:object_r:etc_t or
root:object_r:etc_t

Are these settings correct?  Do I need to run restorecon on them?  or on
all folders in the system?

Thanks!
