I checked more carefully, and sent-mail is not deleted, it does exist  
as an empty file.  However, outbox and trash are also empty files right  
now and are recognized and behave as expected.  Sentbox did have  
"subscribe to new mail check" selected, but deslecting it make no  
apparent difference.
