SELinux is preventing the /usr/sbin/dovecot (dovecot_t) from binding to port

Detailed Description
    SELinux has denied the /usr/sbin/dovecot from binding to a network port
    10143 which does not have an SELinux type associated with it. If
    /usr/sbin/dovecot is supposed to be allowed to listen on this port, you can
    use the semanage command to add this port to a inetd_child_port_t type.   If
    you think this is the default please file a
    http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against the selinux-policy
    package. If /usr/sbin/dovecot is not supposed to bind to this port, this
    could signal a intrusion attempt.

Allowing Access
    If you want to allow /usr/sbin/dovecot to bind to this port semanage port -a
    -t inetd_child_port_t -p PROTOCOL 10143 Where PROTOCOL is tcp or udp.

i am redhat 5 ,and postfix mail,I try allowing:
semanage port -a -t inetd_child_port_t -p PROTOCOL 10143 Where PROTOCOL is tcp
semanage port -a -t inetd_child_port_t -p PROTOCOL 10143 Where PROTOCOL is udp
but it isn't suport for the command
what's wrong?
how can I do it ?
thank you!
