I don't seem to see your definition entry (do you have it created somewhere else?) below is how my entry looks like, edit yours to look like that:
define contact{
contact_name seun
alias Administrator
service_notification_period 24x7
host_notification_period 24x7
service_notification_options w,u,c,r
host_notification_options d,r

Nevertheless, you need to also fix the error SM spotted. To do that, let see what you have post output of the following(you may disguise you url for privacy ;)
cat /etc/hosts, hostname, hostname -f

}
Could you crosscheck the part in bold i think it should be /usr/bin/mail -s (you could cd into /bin to see whether the file mail exist in there)
Also trust your contacts.cfg has been setup properly? if you try the above ensure you restart nagios then try to trigger the notification by shutting down a service you are monitoring. If it still does not work then post output of cat /etc/nagios3/conf.d/contacts_nagios2.cfg (OR cat /etc/nagios3/conf.d/contacts.cfg).

Thanks all for explanation.
May be I need to know something. From the server I installed nagios should I configure local mailserver like postfix or sendmail or I may use email addres that's located on the another server ?
Below are the logs ;

Hi Kwame,
If you determine that you can send email from the CentOS box on which
Nagios is running, then be sure that you have specified the contact
group or contacts option for the service or host that you want to be
notified for when something happens.
For example, to be notified by host specify either contact or a
contact_groups in the host definition:
http://nagios.sourceforge.net/docs/3_0/objectdefinitions.html#host
Or, if by service:
http://nagios.sourceforge.net/docs/3_0/objectdefinitions.html#service
Or, for things like serviceescalation, hostescalation,
http://nagios.sourceforge.net/docs/3_0/objectdefinitions.html
Cheers,
- Hervey
