How to keep ruby on rails script running persistently within rails app on ec2 -

In my application I have a mailman script which checks email for every 60 seconds & amp; Adding Email Content to Rail Database Whenever I run a script "Script / Mailman Server" on my ec2 AMI, it receives an email address by email name. I think Melman scripts should receive an email manually with manual intervention, so I do not want to run the script manually every time, to get the email, it's handled very well in the halo, but not sure That's how it works on EC2.. any help !!! :)
