Many thanks for the reply!
I have done as you suggested and put the 'primary user' account in.
We dont get NDR's now, but the emails still do not seem to reach their
intended reipient.
CAn you shed any light on some of the other settings which may be related:
ie Send Helo instead of EHLO
ETRN/TURN
(or could be as simple as resarting the serveror some servicse before the
other settings take effect etc.

SMARTHOST
As is normal with many ISPs, you'll probably need to authenticate to your
ISP's SMTP server when SENDING mail. In order to accomplish this, you'll
first need to configure Exchange server to use a Smarthost. So, continuing
on with CEICW, at the "Internet E-mail" screen, select Enable Internet
e-mail. On the Email Delivery Method screen, select "Forward all email to
the email server at your ISP". Enter your ISP's SMTP server (e.g.,
mail.yourisp.com).
SMARTHOST AUTHENTICATION
In CEICW you told it to "Forward all email to the email server at your ISP"
(i.e., use the ISP as a Smarthost). Most ISPs require authentication to do
this. To configure authentication, go to:
Server Management | Advanced Management | First Organization (Exchange) |
Connectors | (right click) SmallBusiness SMTP Connector | Properties |
Advanced | Outbound Security | Basic Authentication | Modify.
and enter your authentication credentials. This is usually the primary
account username/password or an email account username/password that was set
up when you signed up with your ISP. Once you've done this, click OK three
times and your Smarthost authentication is done.

I ma running SBS2003 which is setup with pop3/smtp connector to
send/receive
all external emails via an ISP.
Until yesterday all was working OK. Now whenever any of my clients try to
send esternaly they receive an NDR:
The following recipient(s) could not be reached:
<mailto address> on 29/06/2006 12:02
There was a SMTP communication problem with the recipient's
email server. Please contact your system administrator.
<myFQDN #5.5.0 smtp;550 <mailto address>... Relaying denied>
I think I have narrowed this problem down to an SMTP authentication error.
I did this by setting up a standalone machine (connected to my router) and
set up Outlook express to send and receive via my ISP. This works if the
'My
outgoing server (SMTP) requires authentication' box is checked and use the
same settings as I/C server. I f however i deselect this setting, I
receive
exactley the same 550 error.
So the question is how do I configure my SMTP connector in Server Manger
to
do this authentication automatically for all accounts?
Any help would be appreciated!
