[fetchmail]fetchall problem

Hell all, 
My fetchmailrc is something like this
poll gate.polarhome.com proto pop3 nodns
user shantanu is shantanu here
fetchall keep forcecr to * here
But fetchmail is not fetching the mails which which were read previously.
Is it because of fetchall and keep options.
Als, how do i see which message is being fetched at the moment. i fire my 
fetchmail from command line itself.
Thank you.
