MIME and mailcap

[Paul Schmehl]

I'm trying to understand the use of mailcap for MIME translation within a 
mail client.  I installed mail/metamail, which created a .mailcap file in 
my home directory.  That file appears to be a copy of the run-mailcap 
script.  But what does it do?  It seems like it does nothing.

What I'm trying to do is get the mail client to open an image viewer when I 
double-click on a jpeg attachment.  The mail client is designed to source 
the mailcap file from /etc/, /usr/local/etc/ and from ~/.mailcap.

What am I missing here?  What's the best/proper way to do this?
