hello,

i use exim 4.10-8 with SMTP auth. most of the clients work well, exept Novell
Groupwise (latest beta).

and here are my used authenticators:

begin authenticators
cram:
driver = cram_md5
public_name = CRAM-MD5
server_secret = ${lookup mysql{MYSQL_AUTH_CRAM}{$value}fail}
server_set_id = $1

plain:
driver = plaintext
public_name = PLAIN
server_condition = ${if eq{${lookup mysql{MYSQL_AUTH_PLAIN}{$value}fail}}{$3}
{yes}{no}}
server_set_id = $2

login:
driver = plaintext
public_name = LOGIN
server_prompts = Username:: : Password::
server_condition = ${if eq{${lookup mysql{MYSQL_AUTH_LOGIN}{$value}fail}}{$2}
{yes}{no}}
server_set_id = $1
