exim SMTP AUTH

["Antony Gelberg" <antony@antgel.co.uk>]

Hi all,

I'm trying to set up SMTP AUTH with the LOGIN method.  I see AUTH LOGIN as a
response to EHLO.  I have created /etc/exim/passwd with contents:
bob    Bob123

I converted the username and password to base64, for testing:
echo -n '\0bob\0Bob123'| mimencode
XDBib2JcMEJvYjEyMw==


This is what I get:
www:/etc/exim# exim -bh 127.0.0.1

**** SMTP testing session as if from host 127.0.0.1
**** Not for real!

>>> host in host_lookup? yes (*)
>>> looking up host name for 127.0.0.1
>>> IP address lookup yielded www
>>> Alias www.bob.com
>>> Alias localhost
>>> Alias localhost.localdomain
>>> host in host_reject? no (option unset)
>>> host in host_reject_recipients? no (option unset)
>>> host in auth_hosts? no (option unset)
>>> host in sender_unqualified_hosts? no (option unset)
>>> host in receiver_unqualified_hosts? no (option unset)
>>> host in helo_verify? no (option unset)
>>> host in helo_accept_junk_hosts? no (option unset)

Any ideas?  I've looked in the exim docs and have no idea where I'm going
wrong.
