There are always choices. One choice is to read the documentation.
You have (or should have) a complete copy of all the docs in HTML
with your copy of Postfix. These are the same as the ones you will
find at www.postfix.org (except the latter have been updated for
features that are still under development, Postfix 2.7, as well as
for any features added after your particular version.)

The BASIC_CONFIGURATION_README is a good starting point, and you'll
find a useful example in STANDARD_CONFIGURATION_README too. The
SOHO_README might also be useful.

That has been answered, postsuper(1).

Postfix has nothing to do with fetching messages, it is the mail
transfer agent (MTA.) When mail is delivered, Postfix is done with
it and out of the picture.

It could not have been the cause.

Here a bounce is being sent.

This is definitely a problem. No way to guess what it means, with
information you provided.

Hmmm. Perhaps you did something strange with aliases(5) or virtual(5)
aliases (see postconf.5.html#virtual_alias_maps and VIRTUAL_README)
which rewrote the cia.gov sender address to someth...@lan.internal.
Now DNS is suggesting that lan.internal mail should be routed to you,
but you have not listed that domain in any of your address class
definitions (see ADDRESS_CLASS_README for descriptions.)
See DEBUG_README.html#mail (this is the same information as was in
the list's welcome message) if you still have questions.
