message body --> script ?

[Denis Voitenko]

I have a silly idea of writing a small robot that would accept message
bodies in format like

http://www.whateverurlyouwhish.com
http://... [as many urls as you wish]

and reply to it with the content of the web page. I have attempted to do so
by creating an alias like .qmail-robot with content

| /home/robot/script.pl

but something is not working out. Should I pass messages some other way?
