A Postfix null-client does not "receive" any external mail
master_service_disable = inet
inet_interfaces = 127.0.0.1

That's what Postfix null-clients do.

The extra rope provides reliable queue management, sensible recovery when
the remote MTA comes back up, SASL authentication, customizable rewriting
of locally generated mail from root, and other system accounts, ...
In a large corporate environment, a more capable null-client is handy. For
a very small shop, this may not be useful.
I would not recommend any locally queueing MTA on a laptop where
conserving battery power is a priority, there MUAs such as Thunderbird,
that submit directly to a central MSA make more sense.
