easy shell scripting question

I've made with the help of people here this script to filter the ssh attempts:

cat /var/log/messages | grep "authentication failure;" | gawk -F: '{ print $4 }' > /tmp/ssh.txt
sort /tmp/ssh.txt | uniq > /tmp/sshfinal.txt
cat /tmp/sshfinal.txt | gawk -F"rhost=" '{ split($2, a, " |\r\n"); print a[1]; }' | uniq > /tmp/sshfinal.txt

i've added this line to get it via email after a cron setup.

echo -e "Subject:Firewall\nFrom:Server <senderemail\>\n"`cat /tmp/sshfinal.txt` | /usr/sbin/sendmail myemail

The sshfinal.txt file looks like this:

But ofcourse when I receive the email its like this :

it may sounds stupid but how can I change that ?

I know i could do that if i would use \n at the end of each ip in the sshfinal.txt file, but the file is generated by the script each time so I dont know how to do that.
