[Exim] SMTP AUTH as smarthost

Hi all,


I have one intranet and a mail server with SMTP AUTH and my
local machines don't have permission to relay messages to
the mail server. All machines of my intranet are configured
as a smarthost for mail server.

local machine:

smarthost:
driver = domainlist
transport = remote_smtp
route_list = "* my.mailserver.com bydns_a"

and in authenticators configuration:

fixed_plain:
driver = plaintext
public_name = PLAIN
client_send = "^login^password"


The problem is that my local machine does not send the
auth login/password to the mail server. Is this the right
way ? How can I configure this ?


Thanks,

Fabio
