As a side note, if the "to" section of the scrlttr2 file contains a bbdb
link as below

,----
| ** to
|    [[bbdb:Richard%20Stallman][bbdb:Richard Stallman]]
`----


and you have BBDB entry with the address for the above person as shown
below

,----
| Richard Stallman - Free Software Foundation
|          Office: 51 Franklin St
| 		 Boston, MA  02110
| 		 US
|             net: rms@gnu.org

then org-scrlttr2 is intelligent enough to expand the snail mail address
automagically.
