The pipe.pl script provides a way to have POPFile classify messages piped to it by other processes that can then take the classified message and deal with it.

What it does

• Accepts the raw message text (you should include headers) on STDIN
• Classifies the message and inserts the POPFile X-Text-Classification and/or performs Subject line modification as configured in POPFile.
• Emits the now classified message (including new header and modified Subject line) on STDOUT
