Evolution marks mail as deleted.  You can then Expunge (ctrl-e) to 
actually delete them.  Personally, this is the way I like it. 

I took a quick google to see what the procedure was for changing that to 
a 'Move to Trash' folder, but it appears Evolution uses virtual folders 
to emulate a Trash.

Maybe the expunge information is enough for your needs?  I was assuming 
you wanted a Trash folder, with data, to be seen across different clients.
