My general type of exim4 configuration is "satellite" as I just intend 
to relay the outgoing mails to my provider.
Here is my config files :
# cat /etc/exim4/update-exim4.conf.conf
[...]
dc_eximconfig_configtype='satellite'
dc_other_hostnames=''
dc_local_interfaces='127.0.0.1'
dc_readhost='mydomain.com'
dc_relay_domains='*.*'
dc_minimaldns='false'
dc_relay_nets=''
dc_smarthost='smtpauth.provider.fr::465'
CFILEMODE='644'
dc_use_split_config='false'
dc_hide_mailname='true'
dc_mailname_in_oh='true'
dc_localdelivery='mail_spool'

# cat /etc/exim4/passwd.client
[...]
smtpauth.provider.fr:username@provider.fr:password
