I need a perl program that will process email sent to a certain address (like perldesk)

I want it to sort through the email and run a specified program depending on the contents of the email

If this is possible, and you think you can do it, let me know along with price information...

If you would like more details as to what I want the program to do, let me knokw. Right now I just want to see if it is possible.
