Sendmail in a shell script

Someone asked me to write a script that will send mails to a particular email id. I had not used any such script before. So I had to search quite a lot. Here is the simple shell script that will send mail to the specified email ids. Currently it does not support attachments.

#!/usr/bin/ksh
#———————————————————————-
# Name: SendMail
# Purpose: To send mails using the sendmail command
# Usage: SendMail
# Owner: Ketan Joshi
# Setting: Just change the variables at the start of the script to
#          appropriate values. Create a message by modifying the string BODY
#          You can even have html tags in the body.
# Limitation: Currently, this does not support attachments.
#——————————————————————–
#Temporary file for containing the mail message
tmp=/tmp/mail-body-`date +%F`;
touch $tmp && chmod 600 $tmp;
#Set up the various headers for sendmail to use
TO=’ketan.joshi@oracle.com,saurabh.abhishek@oracle.com';
CC=”;
FROM=’ketan.joshi@yahoo.com';
SUBJECT=’Test Mail';
MIMEVersion=’1.0′;
CONTENTType=”text/html; charset=us-ascii”;
#Here write the content of your mail.
BODY=”
<b>Hello from ketan.</b>
This is test mail.
“;

echo Sending the mail.
echo -e “To: $TO” > $tmp;
echo -e “Cc: $CC” >> $tmp;
echo -e “From: $FROM” >> $tmp;
echo -e “Content-Type: $CONTENTType”>>$tmp;
echo -e “MIME-Version: $MIMEVersion”>>$tmp;
echo -e “Subject: $SUBJECT”>>$tmp;
echo -e “Body: $BODY”>>$tmp;

/usr/sbin/sendmail -t < $tmp;

rm -rf $tmp;

    I noticed that this is not the first time you write about the topic. Why have you chosen it again?

    Hello

    This script is works, but at the reciver the mail is recived as a spam, bulk mail.what is the solution for this? Reply..

      add the mail id from which the script sends mail to your address book. This will make sure that the mail is not marked as spam.

    yes thanks for previous Rply. it works now.. but i need to set this script to be run as a cronjob i have set the job as:

    */10 * * * * /root/alertmail.sh

    where as alertmail.sh , contains the above sendmail script
    it is not working on server ? where as manually running shell, it works, what to do for that?

  4. Using python for sending mail gives you additional options and extensibility. Usage of TLS/SSL for smtp servers are supported in python’s library. easy to get arguments via shell also.
