I did think of that, but isn't it rather insecure?

What user is Postfix running as when it attempts to create these lock
files? I thought it was postfix, but doesn't seem to be. If I know the
user trying to create the lock file then I can try and allow access
without making it world writable.

I'm getting the following on startup:

        warning: /var/spool/postfix/etc/localtime and /etc/localtime differ
        warning: /var/spool/postfix/etc/resolv.conf and /etc/resolv.conf differ

Why are there separate copies of these files? Can't I just link to the
main ones in /etc so they'll never 'differ'?
