The following builds on an example in the transport(5) manpage.
With SMTP, this will reject mail during the RCPT TO phase (Postfix
does not generate a boune message). In non-SMTP contexts, Postfix
generates a bounce message when it attempts to deliver mail.
/etc/postfix/main.cf;
transport_maps = hash:/etc/postfix/transport
/etc/postfix/transport:
# The lookup result is indented by one space.
user@some.example
error:5.1.6 This address is out of service. For business please contact
funct...@company.example.net, or n...@private.example.net for
private contact.
This should use a 'fast' lookup mechanism (not LDAP or *SQL) as it
is in the critical path of the queue manager.
