In fact it is possible to use the XUL sort service to sort a 
content-based template.

The mail message list is a custom view so it has special selection 
handling code... I would file an enhancement to apply this to 
dont-build-content trees if nobody else has yet. Otherwise, you would 
have to intercept column clicks, save the selected resources, sort the 
tree and restore the selection.
