Boot slow in starting sendmail

shsir · 08-16-2007, 06:00 AM

When I boot my fc7 every time. Coming to Starting sendmail and will stay here several minutes. What can I do to reduce the boot time.

Are you using sendmail??? if not then; chkconfig --levels 345 sendmail off

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;

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!
