I'm trying to get a dialup linux box client to use an exim server as a
smarthost. The authentication mechanisms on the server work fine as far as
I can tell. They advertise PLAIN and LOGIN AUTH mechanisms upon
connection. However it appears to me the client doesn't bother trying to
authenticate and I end up with a relaying denied.
On the client exim config file I have:
In TRANSPORTS CONFIGURATION
remote_smtp:
driver = smtp
port = 9671
authenticate_hosts = mysmarthost.smarthost.com
In ROUTERS CONFIGURATION
smarthost:
driver = domainlist
transport = remote_smtp
route_list = "* mysmarthost.smarthost.com bydns_a"
In AUTHENTICATION CONFIGURATION
plain:
driver = plaintext
public_name = PLAIN
client_send = ^user^password
And heres the log from a connection:

It doesn't appear to me that the client is attempting to initiate any sort
of authentication. I've got authentication working on the server side with
netscape and outlook clients just fine, however its obviously not working
here. I may be wrong, but I'm assuming I should be seeing the client send
some sort of AUTH command in the above output, but I'm not seeing it.
Is there anyway to test my config file to identify if my client will
attempt authentication with a smarthost server?
Is there anything else in the above that I'm missing?
Before anyone asks, The 'port = 9671' is to get around an ISP that blocks
access to port 25 to anything but their own mail servers. On the server,
port 9671 is redirected to port 25 via an iptable rule.
