If you mean ALL networks (external as well)... DONT!!!
that is unless you are securing it.
If you mean all IP's in a network range I.E Local or VPN
mynetworks=127.0.0.1/8 192.168.16.0/24
you will then need to setup smtpd restrictions if you need help with this please tell me.

dnsproxy
DNSPROXY(1) BSD General Commands Manual DNSPROXY(1)
NAME
dnsproxy -- DNS proxy
SYNOPSIS
dnsproxy [-dhV] [-c file]
DESCRIPTION
The dnsproxy daemon waits for nameserver queries on a user specified address, dispatches these queries to authoritative and recursive name-
servers and forwards the received answers back to the original client.
The options are as follows:
-c file Read configuration from file.
-d Detach from current terminal and run as background process.
-h Show usage.
-V Show version.
If a client from an internal IP address does a recursive lookup the query is forwarded to a recursive DNS server. Authoritative queries and
queries coming from clients in foreign networks are forwarded to an authoritative DNS server.
CONFIGURATION FILE
At startup dnsproxy reads a configuration file specified via the -c option or at the default location of /etc/dnsproxy.conf.
The following keywords are recognized:
authoritative IP
Address of the authoritative nameserver [required].
recursive IP
Address of the recursive nameserver [required].
listen IP
Local address (defaults to 0.0.0.0).
port number
Local port number (defaults to 53).
chroot path
A path to chroot to before starting to answer queries.
user name
A user to change to before starting to answer queries.
authoritative-timeout seconds
Time in seconds when authoritative queries time out (defaults to 10).
recursive-timeout seconds
Time in seconds when recursive queries time out (defaults to 90).
authoritative-port number
Port number on authoritative nameserver (defaults to 53).
recursive-port number
Port number on recursive nameserver (defaults to 53).
statistics seconds
Period between output of statistics (defaults to 3600). Use 0 to disable output of statistics completely.
internal network
Declare networks recognized as internal and thus eligible to do recursive queries. One network in CIDR notation per keyword.
EXAMPLE
authoritative 10.1.1.1
recursive 127.0.0.1
recursive-port 10053
listen 192.168.1.1
port 53
chroot /var/empty
user nobody
internal 192.168.1.0/24
internal 127.0.0.1
STATISTICS
Every hour (by default) dnsproxy logs the collected statistics about its usage to standard error (or syslog when running detached). Statis-
tics look like
ActiveQr AuthorQr RecursQr AllQuery Answered
0 0 0 0 0
TimeoutQ DroppedQ DroppedA LateAnsw HashColl
0 0 0 0 0
and have the following meaning:
ActiveQr
Number of currently active queries proxied to the servers.
AuthorQr
Accumulated number of authoritative queries.
RecursQr
Accumulated number of recursive queries.
AllQuery
Accumulated number of all queries ever received.
Answered
Accumulated number of answered queries.
TimeoutQ
Accumulated number of queries that did not receive an answer in time.
DroppedQ
Accumulated number of dropped queries (e.g. transmission errors).
DroppedA
Accumulated number of dropped answers.
LateAnsw
Accumulated number of answers received after the timeout period.
HashColl
Accumulated number of hash collisions in the query list.
