By send-only, you seem to mean no local mailboxes, all mail is forwarded
to remote systems. That's fine. You can still run an SMTP listener.
The null-client write at:
http://www.postfix.org/MULTI_INSTANCE_README.html#split
explains how to configure a Postfix instance to have all mail sent to a
"smarthost", by making sure that $mydestination (and, but this is the
default $virtual_mailbox_domains) is empty. But you can also not specify
a "relayhost" and use MX hosts for outbound delivery, ...
It also suggests disabling inbound SMTP, but that's optional.
