Playing sound when new mail arrives.

[Dan Murphy]

Hi all.
Back around Christmas, I saw something Chuck Hollenbeck posted here that
would allow you to hear a sound when mail arrived.
I followed the instructions given, but, Chuck, if you're out there, could
you perhaps mail me off list and provide some more details about how to
use procmail for this?
I run fetchmail in daemon mode all the time, but my experience using
procmail is non existent.  thanks.
thanks.
