fetchmail question

[Bikrant]

Hi... I am trying to retrive mails using fetchmail and then deleiver it 
locally using sendmail. I found that fetchmail adds the following header in 
every messages that it retrives from the pop server.

Received: from localhost (localhost.localdomain [127.0.0.1])
        by localhost.localdomain (8.12.5/8.12.5) with ESMTP id i5QIldIr030563
        for <root at localhost>; Sun, 27 Jun 2004 00:32:39 +0545

I am running fetchmail as root user so it has modified the recepient to 
root at localhost. Isn't there any way so that fetchmail retains the original 
recepient ? I tried  -n and --invisible options but they didn't help.

Thanks,
Bikrant
