Hi

In the morning when I check the dmesg I see this error

grsec (root:U:/usr/lib/postfix/pickup) denied access to hidden file /dev/log by /usr/lib/postfix/pickup[pickup:13241] uid/euid:0/0 gid/egid:0/0, parent /usr/lib/postfix/master[master:1464] uid/euid:0/0 gid/egid:0/0

pickup and master has rw permision to /dev/log,but still in log I have access denied, why? Any ideas?
