email firewall/gateway but with root mail

[Farkas Levente]

hi,
i've got a mail firewall/gateway and try to follow the instruction in
http://www.postfix.org/STANDARD_CONFIGURATION_README.html
to disable all local delivery. the only problem with this approach is
that even root's mail are dropped, ie. even if i has a line in
/etc/aliases root:  [hidden email] the locally generated
(daemon) mails still dropped by postfix (even the alias are remote).
so what is the preferred way to disable local delivery but deliver
locally generated daemon's mail to an external email address?
thanks.

if you disable local delivery, then /etc/aliases will not be used.

you can use virtual_alias_maps:

[hidden email]      [hidden email]

next time, shows relevant logs and output of 'postconf -n'.

if i set any of these 3:
mydestination          =
local_recipient_maps   =
local_transport        = error:local mail delivery is disabled
i've got this error:
--------------------------------------------------

if i comment out the above settings then the mail delivered to the
remote server.

there is no reason to set local_recipient_maps to an empty value.

please show output of 'postconf -n'.
