I see. Many thanks. 

Hello all. How can I add or remove addresses from the templates? 

Configuration > Template files.  Select the template you need to edit then edit its template script.

Thanks for the quick response- however, I am not sure where Configuration is. I 

The Configuration pull-down menu.  You are inquiring about templates in Mercury right?

I am not sure. All I knew is that it is Pegasus mail. I believe I have done this before but just cant remember how to access the template address list. I do not see a drop down menu named Configuration. The only choices on the top of the screen are File, Edit, Addresses, Tools, Folder, Window, and Help. 

You posted in the Mercury support forum which explains the confusion.  Repost in the Pegasus Mail support forum
