RE: 5.7.1 domain isn't in my list of allowed rcpthosts

Hi Brett,

Thanks for your information.

I am sorry for the delayed response due to weekend. Please understand that
the newsgroups are staffed weekdays by Microsoft Support professionals to
answer your systems and applications questions. Your understanding is
greatly appreciated!

Have you contacted your ISP to check the SPAM filter service? From the
bounced message, the error information is not reported by exchange server.
You can test send email directly to your exchange server (bypass DNS name
resolution) rather than through ISP to isolate the issue.

I appreciate your time! I am happy to be of assistance to you.

Have a nice day!

Sincerely,

Jenny Wu

Hi Brett,

Thanks for your information. I appreciate your time and efforts to the
issue.

The problem may lies in the SPAM filter service, please contact your ISP
for support. Also let us perform the following test to find the clue.

Please make the e-mail sender to send email directly to your exchange
server (bypass DNS name resolution) rather than through ISP, does the
issue
happen again?

If the sender's email server is exchange, you can let them refer to the
following steps to setup bypass DNS name resolution to test Simple Mail
Transfer Protocol (SMTP) mail flow to your domains.

1. Create an SMTP Connector to the remote domain that you want to send
messages to.
2. When you are local to the remote SMTP server, start a command prompt,
and then run an ipconfig command to verify the Internet protocol (IP)
address of the SMTP server of your domain.
3. Open the SMTP connector properties, click the General tab, and then
type
the IP address of your SMTP server in the Smart Host box.

Note Format the address so that it is enclosed in brackets, for example
"[10.10.250.1]".
4. Stop the Microsoft Exchange Server Routing Engine Service and the SMTP
service.
5. Restart both services.
6. Use the Winroute utility to check for changes to routes.
7. Send test messages to your domain.

When you complete this procedure, Exchange completely bypasses the DNS
service and delivers messages to the remote domain directly through the IP
address. If mail delivery is successful, you may be experiencing issues
with name resolution. Use additional tools to determine if the issue is
caused by records that are returned by DNS to the requesting Exchange
computer, or if the issue occurs because Exchange is not using that
information correctly. Use utilities such as Nslookup to assess
information
that is being passed to Exchange from an internal DNS server and compare
it
to the DNS information that is available from any of the Internet DNS
servers.

For more detail information, you can refer to the following information:

285863 XCON: How to Bypass DNS Name Resolution to Test SMTP Mail Flow to
Remote
http://support.microsoft.com/?id=285863

Does the issue happen again from the sender? If not, that indicates that
problem lies in ISP.

I am happy to be of assistance!

Have a nice day!

Jenny Wu

Hi Brett,

Thanks for your update.

From your exchange server domain name¡¡( methodder.com), I checked the MX
records via http://www.dnsstuff.com/

a.mx.methodder.com. A IN 300 216.17.3.38
b.mx.methodder.com. A IN 300 216.250.187.12

However when I try to telnet to the server, the response is not as
expected. For further analyze the issue, please help me collect the
following information:

1. What is the SBS server external IP address? How many NICs you
installed
on it? What is your SMTP domain?

2. How you setup exchange to retrieve emails? Directly received using
exchange server or received through ISP and then deliver to your exchange
server? I suggest you contact your ISP to check the related
configurations.

3. Please enable message tracking and SMTP logging in your exchange
server
till the issue is reproduced. You can mail me the message tracking log
and
smtp log for analyze. And let me know the information: exact mail sender,
recipient mail address and time when the issue happens.

To enable the Message Tracking logs, please perform the steps in the
following KB articles:

823864 Improved Message Tracking Features in Exchange Server 2003
http://support.microsoft.com/?id=823864

821910 How to troubleshoot for Exchange Server 2003 transport issues
http://support.microsoft.com/?id=821910

Since the issue happens randomly, we need monitor the server till the
issue
is reproduced to find the clue.

You can also try to test your exchange server using telnet command from
external domain. you can refer to the following KB articles:

838049 HOWTO: Telnet to Port 25 to Test SMTP Communication
http://support.microsoft.com/?id=838049

The customer mail content:
====================
Hi, thanks for the response.

How can I tell which server is sending the NDR? I'm not sure if this
mail
is getting to my server or not.

The exchange server domain name is methodder.com. The sender domain name
is random, it happens from various different domains and sometimes they
can
send mail to us, sometimes they get the NDR.

At this point we haven't installed any antivirus or Trend software on
that
server.

Thanks,
Brett

Hi Byerks,

Thanks for your information.

Based on my research, the issue should be lies in the mail sender side.
Please let the sender to check it's configuration. The following
solution
should be processed in the sender side.

I. Please check if the mail sender side uses any external DNS Server.
if
yes, please move all the external DNS servers. You can refer to the
following steps:

a. On the Exchange 2003 server, open Exchange System Manager.
b. Expand Servers -> <servername> -> Protocols -> SMTP.
c. Right click on Default SMTP Virtual Server, and click properties.
d. On the delivery tab, click Advanced button.
e. Click Configure button. Do you see any external DNS servers
configured?
If yes, please remove all the external DNS servers.

II. Based on research, the issue may occur if you are using one
internet
service provider but a third party email provider that is forwarding
the
email. Please perform the following steps to check the issue.

In Outlook 2003 go to Tools > Accounts > view or change existing email
account > change > more settings > out going server tab > my out going
server requires authentication > log on to incoming mail server before
sending email.

III. If the issue persists, please let the customers contact their ISP
to
check if the ISP is different than their email provider.

Hope above information helps! I am happy to be of assistance to you.

Have a nice day!

Hi Byerks,

Thank you for posting here!

I am sorry for the delayed response due to weekend. Please understand
that
the newsgroups are staffed weekdays by Microsoft Support professionals
to
answer your systems and applications questions. Your understanding is
greatly appreciated!

From your description, I understand the issue to be: users randomly
received NDR message (#5.7.1) when they sent mails to your SBS domain.
If
I
am off base, please don't hesitate to let me know.

Before we go any further, please kindly help me collect some
information
to
isolate the issue so that it can be resolved efficiently.

1. Does this problem just occur with some specific users or all the
users?

2. What these users use to send mails? Exchange server or others?

3. Have you installed the ISA server? What is the version?

4. Do you configure any external DNS Server, you may try the following
steps to verify it:

a. On the Exchange 2003 server, open Exchange System Manager.
b. Expand Servers -> <servername> -> Protocols -> SMTP.
c. Right click on Default SMTP Virtual Server, and click properties.
d. On the delivery tab, click Advanced button.
e. Click Configure button. Do you see any external DNS servers
configured?
If yes, please remove all the external DNS servers.

What is more, I would like to suggest you Re-run CEICW (Server
Management
console -> Configuration E-mail and internet connection -> Connect to
the
Internet) to refresh network connection and e-mail server
configuration.
You can refer to the following steps:

A. Click Start, click Server Management.
B. Click To Do List and then click "Connect to the Internet".
C. Click Next, select "Do not change connection type" and click Next.
E. Select Enable firewall and click Next.
F. Ensure E-mail is selected and Click Next.
G. Go through the steps until the Internet E-mail page shows, select
"Enable Internet e-mail" and click Next.
H. Select either "Use DNS to route e-mail" or "Forward all e-mail to
e-mail
server at your ISP". If you select the latter, enter the ISP SMTP
server.
Click Next.
I. Specify to receive e-mail using one or both of the following
methods:

- POP3 Mailboxes
- Exchange

Click Next.

J. Enter your e-mail domain name and click Next. The e-mail domain
name
should match the mail exchanger (MX) resource record maintained at
your
ISP. This must be a registered Internet domain name.
K. Go through the steps to finish the wizard.

For more detail steps, please take a look at the following KB article:
825763 How to configure Internet access in Windows Small Business
Server
2003
http://support.microsoft.com/?id=825763

Then please test the issue, how about the result?

If the issue persists, please let the problematic user enable SMTP
logging
on their SMTP server and then monitor this issue. To enable SMTP
logging,
please follow the steps below:
1. Open Exchange System Manager.
2. Expand to Servers->your_Exchange_server->Protocols->SMTP->Default
SMTP
Virtual Server.
3. Right-click Default SMTP virtual server and then click Properties.
4. Click to select Enable Logging and then click Properties->Advanced.
Select all boxes in the list and then click OK twice.
5. Restart SMTP service.
6. When anyone reported this issue, please collect the corresponding
log
file and send it to me at v-yanniw@xxxxxxxxxxxxx

I appreciate your time! I am happy to be of assistance to you and look
forward to your reply!

Have a nice day!
