[Exim] AUTH problem

Hello,

I have a problem with authenticators. All the authenticators I have
defined in my config file are working fine. The only problem is when
the client connect the server doesn't advertise his ability to do
authentication.

bash-2.05a# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 mailx.ulimit.com ESMTP Exim 3.36 #1 Mon, 08 Apr 2002 23:34:57 -0700
EHLO fo.bar.com
250-mailx.ulimit.com Hello localhost [127.0.0.1]
250-SIZE 3145728
250-PIPELINING
250 HELP


Does someone have any idea why ?

Thanks
Fred
