Duh.  The message is coming from the lib.bmm.Database library -- for  
some reason, my search didn't turn it up.  However, the error has  
nothing to do with the SMTP library -- eliminating that library and  
returning to the old configuration, just one substack, still gives  
the error.  I need to do more research.  Sorry to take up everyone's  
time.
