Victory !!!

Apr 12 19:50:51 localhost deliver(root at vlocalhost):
msgid=<20080412175051.67AD1490087 at localhost.localdomain>: saved mail
to INBOX

Now the security part, i was thinking that this would work also

root at localhost:~# ls -al /usr/lib/dovecot/deliver
-rws------ 1 mail mail 563112 2008-03-31 21:05 /usr/lib/dovecot/deliver
root at localhost:~#

but it doesnt, changing it to user postfix also doesnt work ?
