Fetchmail is running on your local machine, and is using SMTP to deliver 
mail to Postfix, just like it's supposed to. As a result, the IP address 
of the machine sending the SMTP traffic is your system, i.e. localhost.

The only thing that will make MailScanner read the IP address from the 
first Received: header in the message (this is a Postfix-only behaviour 
I seem to remember) is when there isn't an IP address in the message's 
envelope details at all. So if you can get fetchmail to inject the 
message straight into Postfix without using SMTP (you'll have to check 
the fetchmail+Postfix docs to see if this is possible) then MailScanner 
will pull out the IP address you want.

Others more familiar with the deeper innards of fetchmail can probably 
tell us more.
