Though, consider the following:

Will that machine be accessible from outside your LAN?  If so, you need
to take anti-spam steps.

Will that machine be accessible by (potentially) untrustworthy users
within your LAN?  The same precaution applies.

What anti-spam steps could you take?  You could limit SMTP server to
only sending to local addresses, so it can't spam the outside world.
You could limit it to only accepting connections from your LAN, so
outsiders can't get in.  You can use the detection of bogus/forged
addresses for blocking transmission of spam.  You can run anti-spam
software that looks at message content, to block spam...

Don't send private replies to my address, the mailbox is ignored.  I
read messages from the public lists.
