Hi, 

I have a slightly different approach to get notified about emails (sorry, but
I haven't read the former thread). On my machine fetchmail is started via crond
and I have written a script which queries the maildirs and prints the new mails
to stdout. This is then read by my .xinitrc . Just in case you are interested, I
have attached the scripts.

If someone knows some improvements, please don't hesitate to tell me.

bye
