There is an email 'server' to offer web mail that works by intercepting the .forward file via a shell script. I got to thinking this would be very handy for auto-responders, and other stuff (like emailing posts right to the board here).
I need to be able to intercept the email when as arrives and then go dig it out of the inbox. The only step I don't know is how to snag the inbound mail on-the-fly from a activated shell script. I know there is a way to do it.
I found the answer. And with most things Unix, it was simple. Just place the script path in the .forward file you wish to activate. It always helps if you read the man page. (I didn't know there was one for forward)
