I have a shell script which works well:

[snip]
echo "Checking for mail..."
popclient -3 -F -u username -p password -o /var/mail/.jsutton.popclient \
email.host.org

date
echo "Processing mail..."
formail -s procmail </var/mail/.jsutton.popclient
cat /var/mail/.jsutton.popclient >>/home/jsutton/Mail/mail-backup
cat /dev/null > /var/mail/.jsutton.popclient

playbucket /usr/local/ftp/wav/tng/Hailing.wav

Can be. It depends on whether or not you want it to be. 

procmail is a difficult one but it really is necessary to read the man 
pages. If you want something simplier then perhaps the elm mail 
filter, or mh's filter would be a better place to start off. 

I use procmail with mh and exmh - which is fun to set up. :->

Good luck, Joel...
