I would bet you do not recall what you answered to the questions regarding
mail config when installing wheezy. If you have a backup copy of /etc/exim4
you could diff and see.

Regarding receiving mails from root from one machine and routing them to
another you should tell the local exim what to do. It used to ask related
question when configure/reconfigure.

The most simple way to do this is to use the default satellite config. This
is also good for the reason that you usually have one MX for your domain.

Then for the root account you usually define alias to some admin user
account/mailbox.

Just keep it as simple as possible

example of test envs /etc/exim4/update-exim4.conf.conf

MX server

dc_eximconfig_configtype='internet'
dc_other_hostnames='mxhost; test.home; *.test.home'
dc_local_interfaces='192.168.40.40; 127.0.0.1; 127.0.0.1.10025'
disable_ipv6=true
dc_readhost=''
dc_relay_domains=''
dc_minimaldns='false'
dc_relay_nets=''
dc_smarthost=''
CFILEMODE='644'
dc_use_split_config='false'
dc_hide_mailname='false'
#dc_hide_mailname=''
dc_mailname_in_oh='true'


MX client

dc_eximconfig_configtype='satellite'
dc_other_hostnames=''
dc_local_interfaces='127.0.0.1'
dc_readhost='test.home'
dc_relay_domains=''
dc_minimaldns='false'
dc_relay_nets=''
dc_smarthost='192.168.40.40'
CFILEMODE='644'
dc_use_split_config='false'
dc_hide_mailname='true'
dc_mailname_in_oh='true'


On both we do something similar to

cat /etc/aliases
# /etc/aliases
mailer-daemon: postmaster
postmaster: root
nobody: root
hostmaster: root
usenet: root
news: root
webmaster: root
www: root
ftp: root
abuse: root
noc: root
security: root
root: admin_account


Resulting in
From: 
Cron Daemon <root@gw.test.home>
  To: 
root@gw.test.home

From: 
Cron Daemon <root@test.home>
  To: 
root@maistor.test.home

In the MX machine mailbox for the admin_account
