linux - postfix log difference between to and orig_to

I have this log entry:




2015-01-14T09:26:39.448011+00:00 mx01 postfix/error[29736]:
5F8E810015D: to=,
orig_to=, relay=none, delay=0.09,
delays=0.05/0.03/0/0.01, dsn=5.0.0, status=bounced (User unknown in
virtual alias table)




Jan 14 09:26:39 mx01 postfix/error[29736]: 5F8E810015D: to=, orig_to=, relay=none,
delay=0.09, delays=0.05/0.03/0/0.01, dsn=5.0.0, status=bounced (User
unknown in virtual alias table)




what is the difference between to and orig_to in above log? as i am trying to diagnose a bounce back, unable to resolve it.
