Fetchmail doesn't seem to save mail locally

Hi,
I'm using fetchmail-5.6.0 (self-compiled, with "./configure 
--with-kerberos=/usr/athena"), and using kpop to check my mail. Fetchmail 
seems to be able check for messages :


[praveens(_at_)praveen fetchmail-5.6.0]$ /usr/local/bin/fetchmail
1 message for praveens at pobox5.stanford.edu (1725 octets).
reading message 1 of 1 (1725 octets) . flushed

But nothing appears in /var/spool/mail/praveens (my username is praveens); is 
there somewhere else I should be looking? Also, could you cc me since i'm not 
on the list?

Here is my .fetchmailrc:
# Configuration created Tue Feb 13 11:45:19 2001 by fetchmailconf
set postmaster "praveens"
set bouncemail
set properties ""
poll praveens.pobox.stanford.edu with proto KPOP preauth kerberos_v4
       user 'praveens' there with password 'praveens' is praveens here 
warnings 3600
    smtphost  smtp.stanford.edu
    antispam 571 550 501 554

Thanks,
Praveen Srinivasan
