RE: SMTP Server remote queue length alert

Hello Adl,

Thank you for posting in the SBS newsgroup. I'm glad to working with you
again.

First of all, my sincerest apologies for the delay in responding due to
weekend, thanks for the understanding.

Please kindly note the partner managed newsgroups are staffed weekdays by
Microsoft Support professionals. Our goal is to provide a one business day
response to all posts.

For time critical issues (not business down), we encourage you to contact
CSS directly for more immediate assistance:

To continue working with me in the newsgroups, please see the following:

According to your description, I understand that you received this Alert
message "A large number of messages are pending in the e-mail server send
queue". If I have misunderstood the problem, please don't hesitate to let
me know.

To narrow down this issue, please kindly answer and perform the following
questions and steps:

1. First of all, please kindly note that in SBS 2003, the CEICW
automatically creates a SMTP connector for outgoing messages. The
bridgehead defines the Exchange server which can use this SMTP connector to
deliver the outgoing e-mails. SMTP connector is based on SMTP virtual
server and SMTP service. It provides more functions than the SMTP VS does.

More information:
294736 When to create SMTP connectors in Exchange 2000 and later
http://support.microsoft.com/?id=294736

2. What method is used to receive incoming email (POP3 Connector or SMTP
service)? What method is used to send outgoing email (DNS route or ISP
Smarthost)?

3. Please refer to the following information to re-run the CEICW:

a. Run the CEICW and go through the Internet and firewall option.

b. In the Internet E-mail tab, please click to "Enable Internet E-mail".

c. In the Email Delivery method page, please choose the correct email
delivery method. If you need to forward internet email to your ISP
Smarthost, please input the Smarthost address correctly. If you use DNS to
route emails, please choose this option.

Note: If you choose to forward emails to the ISP's email server (smart
host), you need to type the FQDN of the ISP's email server. If your ISP
provides you the IP address of their email server, for example,
12.34.56.78, you should type the IP address as "[12.34.56.78]" (without the
quotation marks) on the connector's properties page.

d. In the E-mail Retrieval Method page, specify to receive e-mail using
one or both of the following methods:

- POP3 Mailboxes
- Exchange

Click Next.

e. In the E-mail Domain Name page, enter your registered e-mail Internet
domain name, (i.e. domain.com). 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.

f. If you are using the POP3 Connector to retrieve incoming email, in the
POP3 Mailbox Accounts page, click Add and add the appropriate POP3
mailbox accounts, then click Next.

g. Input the correct information in the rest page and finish the wizard.

For delivering the internet emails, if you have hardware router, you should
make sure the Outbound TCP port 25 is opening. For your ISP configuration,
you ISP should allow TCP port 25 outbound communication.

If your SBS server uses ISP smarthost, I would like to bring the following
article to your attention

from

2003
http://support.microsoft.com/?id=825763

4. If you're using POP3 connector, it will also cause open relaying.
Please check whether KB 835734 solves the problem.

Many unexpected outbound e-mail messages appear in the SMTP queue in Small
Business Server 2003

More information for your reference:
You can follow this KB to block open SMTP relaying.
How to block open SMTP relaying and clean up Exchange Server SMTP queues in
Windows Small Business Server
http://support.microsoft.com/kb/324958

5. >> 1) How to track down their source
2) How to stop them from occuring
3) How to delete the messages and queues that are already out there

To check it, open the Exchange System Manager, go to Servers -> ServerName
-> Queues, double-click "SmallBusiness SMTP Connector - cia.gov" or
"SmallBusiness SMTP Connector - hidaho.com". In the dialog box, click "Find
Now" button, double-click these emails, you can find these messages'
detailed properties, such as: Sender, Subject, Recipients, etc. Right-click
it, choose "Delete (with NDR)" or "Delete (no NDR)" option to delete these
messages.

As you mentioned "I am unable to delete the mail in these queues (the
delete option is greyed out), and I can't seem to find out any more info on
the emails (there is no sender, no subject, etc.)", please kindly make a
screen shot of it, and then attach it in your reply.

6. If the issue persists, please enable SMTP logging and gather SMTP log
to troubleshoot the issue:

A. Open Exchange System Manager, expand Servers -> <Server name> ->
Protocols -> SMTP, right-click "Default SMTP Virtual Server" and click
Properties.

B. Under the General tab, check the option "Enable Logging".

C. With "W3C Extended Log File Format", click "Properties".

D. Under "General Properties", make sure "Use local time for file naming
and rollover" is CHECKED.

E. Switch to the "Extended Properties", and then select to enable All the
logging Options.

F. Click OK to apply the modification.

G. Right-click Default SMTP Virtual Server and click Stop.

H. Right-click Default SMTP Virtual Server and click Start to restart the
SMTP server.

I. Reproduce the issue, repeat step G to stop Default SMTP Virtual Server,
copy out or zip the SMTP log files in the
"%systemroot%\system32\logfiles\SmtpSvc1" folder, and then restart the
"Default SMTP Virtual Server".

I appreciate your time and cooperation. If anything is unclear, please feel
free to let me know. I am looking forward to hearing from you.

Best regards,

Nathan Liu (MSFT)
