Do you use sendmail as an SMTP server? If not, just remove it at all by command:

su -c 'yum remove sendmail -y'

Thanks Lenard. Now it's OK.I use
Code:
chkconfig --levels 345 sendmail off
sendmail is off at starting. And I think when I want to use it again,I can use
Code:
chkconfig --levels 345 sendmail on

Advance,I want to know why the sendmail is so slow, I open the bash script : /etc/rc.d/init.d/sendmail ,like this
Code:
start() {
	# Start daemons.

	echo -n $"Starting $prog: "
	if test -x /usr/bin/make -a -f /etc/mail/Makefile ; then
	  make all -C /etc/mail -s > /dev/null
	else
	  for i in virtusertable access domaintable mailertable ; do
	    if [ -f /etc/mail/$i ] ; then
		makemap hash /etc/mail/$i < /etc/mail/$i
	    fi
	  done
	fi
	/usr/bin/newaliases > /dev/null 2>&1
	daemon /usr/sbin/sendmail $([ "x$DAEMON" = xyes ] && echo -bd) \
			$([ -n "$QUEUE" ] && echo -q$QUEUE) $SENDMAIL_OPTARG
	RETVAL=$?
	echo
	[ $RETVAL -eq 0 ] && touch /var/lock/subsys/sendmail

	if ! test -f /var/run/sm-client.pid ; then
	echo -n $"Starting sm-client: "
	touch /var/run/sm-client.pid
	chown smmsp:smmsp /var/run/sm-client.pid
	if [ -x /usr/sbin/selinuxenabled ] && /usr/sbin/selinuxenabled; then
	    /sbin/restorecon /var/run/sm-client.pid
	fi
	daemon --check sm-client /usr/sbin/sendmail -L sm-msp-queue -Ac \
			-q$SMQUEUE $SENDMAIL_OPTARG
	RETVAL=$?
        echo
        [ $RETVAL -eq 0 ] && touch /var/lock/subsys/sm-client
        fi

	return $RETVAL
}
I find every time it will do make,
Code:
	if test -x /usr/bin/make -a -f /etc/mail/Makefile ; then
	  make all -C /etc/mail -s > /dev/null
I think it's the reason of boot slow. I can't sure the script is good one but it's fedora 7 default. Can we change it better and make boot faster?

Once sendmail is configured it is fast, unless you are running an email server you do not need it.
Many desktop and laptop users do not need or use it., but if your interested then visit;

http://tldp.org/

And review documentation like:

I faced this problem once and it is resolved once I put the hostname entry in /etc/hosts file alongwith the system IP. The issue was occuring due to incorrect hostname resolution.

True, it's real classic and always the first file to look at when it won't start quickly.

Yes, I opened the file /etc/hosts. Then I found one line
Code:
192.168.0.10 myhost
It is added before by myself when I configed my network. I added '#' at the header. Now sendmail start quickly.

Thanks everyone!
