The setting in question appears to be "unknown_local_recipient_reject_code".  
Postfix's main.cf has the following section:

# The unknown_local_recipient_reject_code specifies the SMTP server
# response code when a recipient domain matches $mydestination or
# $inet_interfaces, while $local_recipient_maps is non-empty and the
# recipient address or address local-part is not found.
# The default setting is 550 (reject mail) but it is safer to start
# with 450 (try again later) until you are certain that your
# local_recipient_maps settings are OK.
#unknown_local_recipient_reject_code = 550

I migrated to a new server last week, and had it set to 450.  After
changing it to 550 it works as expected.  Thanks for the help.
