[exim] list smarthosts

Hi all,
I my /etc/exim4/exim4.conf.template file, i got:

   remote_smtp_smarthost:
     debug_print = "T: remote_smtp_smarthost for $local_part@$domain"
     driver = smtp
     hosts_try_auth = <; ${if exists{CONFDIR/passwd.client} \
         {\
         ${lookup{$host}nwildlsearch{CONFDIR/passwd.client}{$host_address}}\
         }\
         {} \
       }

I would like to have something like:

   remote_smtp_smarthost_server_one:
     debug_print = "T: remote_smtp_smarthost_server_one for $local_part@$domain"
     driver = smtp
     <the right option>: <ip or hostname of server_one>

   remote_smtp_smarthost_server_two:
     debug_print = "T: remote_smtp_smarthost_server_two for $local_part@$domain"
     driver = smtp
     <the right option>: <ip or hostname of server_two>

   remote_smtp_smarthost_server_three:
     debug_print = "T: remote_smtp_smarthost_server_three for $local_part@$domain"
     driver = smtp
     <the right option>: <ip or hostname of server_three>

This is in order to use this:

I can make my script return:
ACCEPT TRANSPORT=remote_smtp_smarthost_server_one
or
ACCEPT TRANSPORT=remote_smtp_smarthost_server_two
or
ACCEPT TRANSPORT=remote_smtp_smarthost_server_three

In my case no server requires SMTP AUTH.

Thank you.
