Hm, interesting corollary question. If you have a valid DBA on file, is it OK to use that name in your domain registrations? It's certainly acceptable to use a corporate or governmental name.
Last time I looked, mail delivery to PO boxes wasn't restricted to the named box owner. So getting the box and using the box are almost completely unrelated.
@ JohnRoy, it's totally possible I have got this mailing lots of times before but never happened to notice it. Then again, it's possibe the service has only just reached my neck of the woods ;)
