[Bro] Redefining the email application

[James Lay]

Hey All,

I've been trying to figured out how to get a different application as 
the sendmail app.  I've not been able to find anything for this, so I'm 
coming here for an assist.  If not being able to redefine sendmail to 
something different, is there a way I can instead fire off a script that 
will run my email application instead?  I've looked at:

For a while now, but I'm not able to figure it out.  Thanks for any 
assistance.

James
