By default, the Postfix SMTP server invokes the proxymap service for local user lookup, because the default local_recipient_maps setting looks like this: local_recipient_maps = proxy:unix:passwd.byname $alias_maps Try, as a root user: postmap -q nosuchuser proxy:unix:passwd.byname postmap -q root proxy:unix:passwd.byname I suspect that your proxymap service is busted.
