Hi Suresh,

I had the same problem. Now after some reconfig I re-wrote an excisting script. This is what I re-use for each program that needs to mail something.
Hope you understand it a little, it's a cool one.

Regs David
Code:
#!/bin/ksh

# We have to invoke a mailer that has no escape possibilities...
#
# The only one I know of would be sendmail, but this is very ugly
# to invoke directly because we have no control of To: and
# Subject: lines...
#
# This wrapper writes some of the Header-Fields before forwarding the
# mail itself in the body
#
# usage: start-mail mailaddr subject

# you might want to change the following line to set a sepcific from: address
#sender=`/usr/bin/id|/usr/bin/sed 's/.*(\(.*\)) .*/\1/'`
sender='root@'`/usr/bin/hostname`

# it's a bad idea to use temporary files with predictable names that are
# located in a world-writable /tmp dir because other local users may create
# sym-links pointing to another file...
#
# better use a tmp-dir that is only accessible by the logsurfer user
# change the following line!
# example: TMP=/home/logsurfer
TMP=/tmp

recepient="$1"
subject="$2"
message="$3"

if [ $# -eq 0 ]; then
	echo 'usage: start-mail mailaddr subject' 1>&2
	exit 1
fi

/bin/rm -f $TMP/start-mail.$$

echo "From: $sender" > $TMP/start-mail.$$
echo "To: $recepient" | /usr/bin/tr -cd '[\040-\176]' >> $TMP/start-mail.$$
echo "" >> $TMP/start-mail.$$
if [ $# -gt 1 ]; then
	shift
	echo "Subject: $subject" | /usr/bin/tr -cd '[\040-\176]' >> $TMP/start-mail.$$
	echo "" >> $TMP/start-mail.$$
else
	echo "Subject: (no subject given - logsurfer output)" >> $TMP/start-mail.$$
fi
echo "" >> $TMP/start-mail.$$
echo "$message" | /usr/bin/tr -cd '[\040-\176]' >>/$TMP/start-mail.$$
echo "\n." >>/$TMP/start-mail.$$


cat $TMP/start-mail.$$ - | /usr/lib/sendmail -odq -t

/bin/rm -f $TMP/start-mail.$$

mailstats

MAILSTATS(8)						      System Manager's Manual						      MAILSTATS(8)

NAME

       mailstats - display mail statistics

SYNOPSIS

       mailstats [-c] [-o] [-p] [-P] [-C cffile] [-f stfile]

DESCRIPTION

       The mailstats utility displays the current mail statistics.

       First,  the  time  at which statistics started being kept is displayed, in the format specified by ctime(3).  Then, the statistics for each
       mailer are displayed on a single line, each with the following white space separated fields:

	      M 	  The mailer number.
	      msgsfr	  Number of messages from the mailer.
	      bytes_from  Kbytes from the mailer.
	      msgsto	  Number of messages to the mailer.
	      bytes_to	  Kbytes to the mailer.
	      msgsrej	  Number of messages rejected.
	      msgsdis	  Number of messages discarded.
	      msgsqur	  Number of messages quarantined.
	      Mailer	  The name of the mailer.

       After this display, a line totaling the values for all of the mailers is displayed (preceded with a ``T''),  separated  from  the  previous
       information by a line containing only equals (``='') characters.  Another line preceded with a ``C'' lists the number of TCP connections.

       The options are as follows:

       -C     Read the specified file instead of the default sendmail configuration file.

       -c     Try to use submit.cf instead of the default sendmail configuration file.

       -f     Read the specified statistics file instead of the statistics file specified in the sendmail configuration file.

       -P     Output information in program-readable mode without clearing statistics.

       -p     Output information in program-readable mode and clear statistics.

       -o     Don't display the name of the mailer in the output.

       The mailstats utility exits 0 on success, and >0 if an error occurs.

FILES

       /etc/mail/sendmail.cf	The default sendmail configuration file.
       /var/lib/sendmail/statistics
				The default sendmail statistics file.
       /etc/mail/statistics	The symbolic link to the statistics file.
