I have a POP3 email account, that I do not use anymore. It is on a server out of my control.
Several of my contacts keep on sending email to that address, though I told them. So I decided to set an autoresponse saying "I do not read at this address anymore, write to that other address".
I need a little process running on one of my always-up machines that fetches emails from the server and answers, to that coming from one of my contact, with a standard response.
I am looking for a solution simple to setup, like fetchmail + mailx + some bash scripting.
