Thanks very much paul
that was a big help!
but i still cant make any sense out of these ones..
48: if ! test -f /var/run/sm-client.pid ; then
if the file /var/run/sm-client.pi does not exist (see "man test")
49: echo -n $"Starting sm-client: "
Write "Starting sm-client: " to screen
50: touch /var/run/sm-client.pid
Create empty file /var/run/sm-client.pid
51: chown smmsp:smmsp /var/run/sm-client.pid
And change its ownership to user smmsp, group smmsp. This is done because the
sendmail Message Submission Program (used for sending mail from your machine)
runs as un unprivileged user and group smmsp, and would not otherwise have
permission to create a file in directory /var/run
52: daemon --check sm-client /usr/sbin/sendmail -L sm-msp-queue -Ac
\
53: -q $SMQUEUE $SENDMAIL_OPTARG
Start another instance of sendmail, writing log entries (/var/log/maillog)
with tag "sm-msp-queue" (-L sm-msp-queue), running as the Message Submission
Program (-Ac), processing the submission queue every $SMQUEUE time period (-q
$SMQUEUE), and with other options defined by $SENDMAIL_OPTARG
54: RETVAL=$?
55: echo
56: [ $RETVAL -eq 0 ] && touch
/var/lock/subsys/sm-client
As before.
The Message Submission Program takes mail generated locally and submits it to
the main sendmail server (started earlier in the initscript) for sending to
its ultimate destination. Two instances of sendmail, running as different
users, are used for security reasons.
