Mail sitting in "message pending submission" queue for 6-8 minutes

Mail sitting in "message pending submission" queue for 6-8 minutes

Post by WmUgSm9rY » Sat, 03 Mar 2007 05:28:43

I have a SBS 2003 setup running Exchange 2003. All has been weel up until 2
days ago. I installed ISA server from the Premium Tools then realised that
it would be more prudent to install this in a VM / Test environment. Anyway,
I uninstalled ISA.

My problem now is that when email is processed, regardless of whether it is
internal / external, it sits in the "message pending submission" queue for
about 6-8 minutes and then delivers as normal.

I turned on message tracking and I can see that the pause is between:-

03/01/07 10.00 SMTP; Message submitted to advanced queuing
03/01/07 10.06 SMTP; Started message submission to advanced queuing

There is no longer an AV application on the server as this is handled by a
barracuda spam filter.

Can anyone offer me any ideas as how to resolve? This is probably my last
stop being doing a migration to another SBS Server which will be the waste of
a good weekend.

Thanks in advance

Thanks for posting in our newsgroup.

From your description, I know that when email is sent, regardless of it is
from internal or external, it stays in the "message pending submission"
queue for about 6-8 minutes and then delivers as normal. If I am off-base,
please don't hesitate to let me know.

Please take the following steps to see if the problem can be resolved:

Step 1: Please make a Force Connection, will the issue still occur?

1. Open Exchange Server Manager.
2. Expand to Domain(Exchange)->Servers->Servername->Queues.
3. Right click Message pending submission and then select Force connection.

Step 2: Please restart Microsoft Exchange System Attendant, will the same
issue reoccur?

1. Run Services.msc under command prompt.
2. Select Microsoft Exchange System Attendant and then click Restart on the

Step 3: Make a clean boot. The problem can be caused by some third party

1. Click Start->Run...->type msconfig and press Enter.
2. Click Services tab and select Hide All Microsoft Services and Disable
All third party Services.
3. Click Startup tab and Disable All startup items.
4. Click OK and choose Restart.
5. After reboot, check whether the problem still occurs.
6. If there are no more problems, please use the above steps to enable
services and startup items one by one in order to figure out the root cause
of this issue.

Step 4: Since the problem began to occur after you install and then
uninstall ISA 2 two day ago, the problem may be caused by network and
Exchange configuration. Please rerun the CEICW wizard.

1. Run the CEICW and configure the network settings.
2. Go through firewall option.
3. In the Internet E-mail tab, please click to "Enable Internet E-mail".
4. 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,, you should type the IP address as "[]" (without the
quotation marks) on the connector's properties page.

5. In the E-mail Retrieval Method page, check the "Use the Microsoft
Connector for POP3 Mailboxes" check box, click Next.
6. In the E-mail Domain Name page, enter your registered e-mail Internet
domain name, (i.e.

Note: Considering the current condition, please input the ISP POP3 email
domain name (i.e.

7. In the POP3 Mailbox Accounts page, click Add and add the appropriate
POP3 mailbox accounts, then click Next.
Note: Please delete the POP3 email account in the Outlook client.
8. Input the correct information in the rest page and finish the wizard.

Thanks for updating.

I am sorry for the delay.

After researching the logs and MPS Report, I found DNS Event ID 4004. This
may be the cause the issue. According to my experience, this kind of issue
often occurs if there is some inaccurate information in the system DNS
database or it is unable to get some required information from the database.

To resolve the problem, please try to remove the _msdcs zone and subfolder
and then re-register this information. Then check if this issue persists.

Note: Please backup your server prior to the following steps as we need to
remove some information from DNS.

1. Open DNS management console.
2. Expand "Forward Lookup Zones".
3. Check if the _msdcs.domain.local zone exists. If so, delete it.
4. Check if the _msdcs subfolder exists under the domain.local zone. If
so, delete it.
5. Open Services console from Administrative Tools.
6. Stop Net Logon service and then restart this service. (This will
recreate the zones and subfolders required for AD)
7. Run the following command under Command Prompt.

Then please monitor the Exchange server to see if the problem can be

If you need further assistance, please don't hesitate to let me know.
