Evolution Mail Print on arival

Hi I was wondering if anyone has gotten this to work. It could be really helpful for me to have this functionality.

The rule I had in mind was

< time ='s +or- a minute or two >
or how ever often I set it up to get messages
< and the message ='s unread >
than
< | to cups >
and
< copy to /var/log/printed/emails >

I've just never done anything like this before and was wondering if it would work that simply.
and what cups driver should I pipe to.

/usr/share?
/usr/local?
Or sbin or some other place.
