You have two rules there:

if (/(X-Original-To):.*lists@mydomain\.com\.au/)
{
 to $LISTS
}

and

if (/^(To|Cc|Bcc):.*michaeldaly@internode\.on\.net/)
{
 to $INTERNODE
}


The first message has a header:

To: [email protected]

This would be matched by the second rule.

Your second message's headers:

From: [email protected]
To: [email protected]

This does not match either rule.

Just save the email message in a file, and run

maildrop [options] <$filename

maildrop would attempt to deliver the message to the mailbox of the system  
user that invoked maildrop.

To have maildrop attempt to deliver the message to some other mailbox, run  
it as root, and include the -d option

maildrop -d mailboxname <$filename

Including the -V option:

maildrop -V 9 <$filename

or

maildrop -V 9 -d mailboxname <$filename
