Executing command upon receiving email

[hakkrdan]

Hello, all -

I'm trying to make an application in which qmail receives a message, and executes a command via pipe.

Not being familiar with qmail at all (mostly sendmail and Postfix), I do not know where to begin. On top of that, I am deathly afraid of messing with anything too much, because if I do, Plesk will surely freak out.

So what I am asking is, how might I establish a setup for a single email address that executes said command upon recieving mail? I am not entirely familiar with the qmail setup wth Plesk, so I am not even going to attempt this just yet.

Any help would be appreciated.

Thanks
