SMTP-Proxy with smarthost that needs authenticatio

One of our customers uses T-DSL-Business together with the Astaro 4.007. We have to use a relay-server, otherwise no mails can be delivered to T-Online-Adresses.
The problem is, that the relay-server of DSL-Business needs SMTP-Authentication. How can I implement the authentication into the SMTP-Proxy. I do not need SSL-Transfers.
I read the Thread "SMTP-Relay with Authentication". Are the steps, mentioned in the thread, the right way and suitable for my problem?
Thx.

Since nobody is talking to me, I have to talk to myself...

I just implemented the steps which are described in the thread "SMTP-Relay with Authentication" but without success. First I got the message "auth name missing". After chainging some things in the exim.conf-default the message disappeared. But the authentication still does not work.
I give you an excerpt from the log file:

Code:

I also placed an EHLO on the mailto.t-dsl-business.de:

Perhaps these lines can help you...???
And finally the last version of the transports and auth sections of exim.conf-default:

Code:

 # ---------- Transports section ---------------------------------------
begin transports

# we use SMTP only
remote_smtp:
  driver = smtp
  hosts_require_auth = 62.156.147.75
  hosts_avoid_tls = *

 ---------- Auth section ---------------------------------------------
begin authenticators

# plain auth (should only be used with SSL)
#plain:
#  driver = plaintext
#  public_name = PLAIN
#  server_condition = "${if pam{$2:$3}{1}{0}}"
#  server_set_id = $2
#  client_send = "^username^password"

# login auth (should only be used with SSL)
login:
  driver = plaintext
  public_name = LOGIN
  server_prompts = "Username:: : Password::"
  server_condition = "${if pam{$1:$2}{1}{0}}"
  server_set_id = $1
  client_send = "username : password"

I had a look at the Exim-Documentation but I did not really understand a lot. So I hope, somebody can help me to solve this problem.

Thx.
