Off Topic: call a perl script

[Carlo Gibertini]

Hello,

I need to call a perl script every time a message arrives at one mail box on
qmail.

reading the docs I found that creating a .qmail file in the directory of the
user with "|/my_program" will call the program.

This work but I cannot receive the message in stdin...
(Obs: my perl is very bad too)

If some good soul can send me a example perl script that gets the content of
the message, i will apreciate...


thanks,

Carlo
