"Trigger" when fetching mails via pop

Hi,

Im currently using courier as POP3 server to get my mails from my server and thinking about doing something like the GMX spamreport.
I don't if you "not german" guys know gmx, so i'll describe the spamreport shortly: gmx is a mail service and the first time per day you ask for mails via pop, an spamreport is generated an send to you along with "normal" mails. so you only get one every day.

Im wondering how this works and want to do a similar thing for a project of mine. So how can you start a program wenn somebody ask the server for mails via pop3?
When receiving emails with postfix you can easily set

Code:

mailbox_command = procmail ...

and procmail then does what you told it to do. How can this be done with an POP server like courier?

thanks in advice!

Well, I would start by reading the courier docs and see if there is a hook for it there like postfix...

You can also write a wrapper script to call the command. For example:

I use popper on my system so, I move popper to popperX and create a bash script called popper:

Code:

#!/bin/bash
# run your gmx program
/usr/bin/gmx
# now run the 'real' popper
/usr/bin/popperX

However, this will not work if you run your pop3 in server mode, rather than from xinetd or whatever.
