Hi,

I am working with a web site that uses CDONTS from a function in a Com+
component to send mail to clients after sign up etc, as well as sending
clients mail to support from a web form.

A virtual default SMTP server is running in !!S (6.0)

We have moved the system to a new server (Windows 2003 Server as the
previous installation) and the mail worked fine a few days. Now we cannot
send any mail from the system.

SMTP is not my speciality, I am working with the databases and system
design, so I desperately need help to get this working.

The settings are as follow:
The server (name "global") is set up as a member of Workgroup, not part of
any domain or active directory.

In SMTP Virtual server:
Access > Authentication: Anonymous access
Access > Connection: All computers
Access > Relay: The IP address for global and also checked "Allow all
computers which successfully authenticate..."

Delivery > Advanced > Fully qualified domain name: global
Delivery > Advanced > Smart Host:[IP address to our mail server]

At first all e-mail were found in the queue folder. After setting up the ip
for our mail server (from EmailArchitect) as Smart Host all mail disappeared
from the queue, but we get a reply on each mail;
From: postmaster@global,
Subject: Delivery Status Notification (Failure)
Body: "Delivery to the following recipients failed..."

The error in the attachment is like:
Reporting-MTA: dns;global
Received-From-MTA: dns;global
Arrival-Date: Tue, 12 Jun 2007 11:37:26 +0200

Final-Recipient: rfc822;lage@hotmail.com
Action: failed
Status: 5.5.0
Diagnostic-Code: smtp;501 local user must be authenticated at first.

I am grateful for any help. This is an online running web site... I have
searched on Google and Microsoft, but cannot find relevant information about
this error message.

That points to a DNS issue.  To troubleshoot SMTP, you have to understan=
d  =

DNS, as the two are tightly linked on the public net.

What is the IP address(es) of the DNS servers used by your mail server  =

(Control Panel-Network-TCP/IP).  Are they both accessible from the  =

server?  Can they both resolve MX records for remote domains?  Run  =

'nslookup -q=3Dmx google.com <DNS server IP>' for both servers from a  =

command prompt and post results.

Also, 'global' is not an acceptable FQDN: you want to use the true,  =

publicly resolvable hostname + domain of the machine.  However, while so=
me  =

servers will block or suspect your mail because of this error, it is not=
=

responsible for your widespread delivery problems.

Eh... you don't put the server's own IP as the Smart Host.  That's
creating a mail loop.  SH is used when you want to defer to another server
for remote delivery.  Deferring to yourself means the mail will never
leave.
