Ah well, answered my own question, and as usual, PEBKAC.

Postfix on both the systems I tried this on had a custom name in the
myshostname field, but the same hostname was not included in
mydestination.  As a result, e-mail sent to a username with no domain
specified were bravely trying to be sent to username at myhostname, which
went nowhere.
