I too would be interested.  This is very easy using an ms outlook client, and can even be set as a configuration push in a ADS/Exchange environment, but I have not found anything outside that that lets you do it and was still smart about when/how it  should use it.

 

 

This is off topic but I wonder if anyone on the list knows of any application that will let design a business letterhead that becomes the default form for email. Thanks for any input. Mike Enriquez
