[exim] smtp authentication with outlook express

HI,

I'm having a world of grief trying to get smtp authentication working
with outlook express. It works with outlook and thunderbird (though I
believe they use the plain authenticator not the login authenticator)
and I can get a successful authentication using exim -d -bs

Any ideas where I am going wrong? It is as if OE does not see that there
is an authentication scheme available as the error message that I get
back is a "550 - unable to relay message"

Here is the authenticator I am using:

login_server:
   driver = plaintext
   public_name = LOGIN
   server_prompts = Username:: : Password::
   server_condition = ${if ldapauth \
        {user="mail=${quote_ldap:$1},o=${extract{2}{@}{$1}},LDAPBASE" \
        pass="$2" \
        ldap://LDAPSERVER/}{yes}{no}}
   server_set_id = $1

Where LDAPSERVER is the ip address of the of the ldap server and
LDAPBASE is "o=email,dc=accesst,dc=com"


All the googleing I have done points to it usually being a problem with
the server_prompt but as far as I can see I have got it correct (tried
with and without double quotes).

Regards,

Pat
