One way: use smtpd_command_filter, and replace recipients without
domain.
Crude example:
/etc/postfix/main.cf:
smtpd_command_filter = pcre:/etc/postfix/command_filter
/etc/postfix/command_filter:
/^(RCPT\s+TO:\s*<)([^@]+)(>.*)/ $1$2@blackhole.local$3
You can test this with the postmnap command before deploying.
