[Exim] esmtp authentification

Well.. I have looked at and tried adding the following to my exim.conf

# $2 = user name : $3 password
plain:
driver = plaintext
public_name = PLAIN
server_condition = "${if pam{$2:$3}{1}{0}}"
server_set_id = $2

login:
driver = plaintext
public_name = LOGIN
server_prompts = "Username:: : Password::"
server_condition = "${if pam{$1:$2}{1}{0}}"
server_set_id = $1


This is based on config.samples/CO34

The following error is presented when sending mail:
