The script was copied from the link http://linuxshellaccount.blogspot.com/2008/04/shell-script-to-send-mail-using-bash.html which describes networking with the help of file descriptors.
I just added a smtp authentication part.
Please ensure that others do not have access to your bash history for security reasons.
Usage
sh mail.sh report@yourserver.com youremail@gmail.com yourserver.com yourmailserver.com filecontainingmessage email@yourmailserver.com youremailpassword

then
echo "Usage: $0 FromAdress ToAdress Domain MailServer MailTextFile AuthEmail AuthPass"
exit 1
fi
from=$1
to=$2
domain=$3
mailserver=$4
mailtext=$5
authemail=`echo $6|openssl enc -base64|awk 'sub("..$", "")'`
authpass=`echo $7|openssl enc -base64|awk 'sub("..$", "")'`
if [ ! -f $mailtext ]
then
echo "Cannot find your mail text file. Exiting..."
exit 1
fi
exec 9<>/dev/tcp/$mailserver/25
echo "HELO $domain" >&9
read -r temp <&9
echo "$temp"
echo "auth login" >&9
read -r temp <&9
echo "$authemail" >&9
read -r temp <&9
echo "$authpass" >&9
read -r temp <&9
echo "Mail From: $from" >&9
read -r temp <&9
echo "$temp"
echo "Rcpt To: $to" >&9
read -r temp <&9
echo "$temp"
echo "Data" >&9
read -r temp <&9
echo "$temp"
cat $mailtext >&9
echo "." >&9
read -r temp <&9
echo "$temp"
echo "quit" >&9
read -r temp <&9
echo "$temp"
9>&-
9<&-
echo "All Done Sending Email. See above for errors"
exit 0
When you run the script you should get a output similar to the following output.
235 2.7.0 Authentication successful
250 2.1.0 Ok
250 2.1.5 Ok
354 End data with
250 2.0.0 Ok
If you get an error like AUTH command used when not advertised
