Can't rebuilt aliases.db file...?

[Timothy Horie]

Hello,

I'm trying to rebuild my /etc/mail/aliases file after changing it but it 
isn't working.

[EMAIL PROTECTED]:/etc/mail# ls -al aliases*
-rw-r--r--  1 root  wheel  1582 Jun 23 00:35 aliases
-rw-r--r--  1 root  wheel     0 Jun 23 00:35 aliases.db
[EMAIL PROTECTED]:/etc/mail# touch aliases
[EMAIL PROTECTED]:/etc/mail# newaliases
[EMAIL PROTECTED]:/etc/mail# ls -al aliases*
-rw-r--r--  1 root  wheel  1582 Jun 23 00:35 aliases
-rw-r--r--  1 root  wheel     0 Jun 23 00:35 aliases.db

Can someone give me some hints? The aliases.db file isn't supposed to be 
0 bytes.

Thanks,
Tim
