Re: Outbound email messages are sent multiple times

Hi Charlie,

If I understand correctly, the issue exists only when you sent emails to
multiple external emails address.

The root cause might be caused by many factors, in order to isolate the
issue, we may need to gather some more information:

1. Do you encounter any problem when sending emails to multiple internal
users?
2. If you only send to less than 100 external email address, do you
encounter such issue or not?
3. Please also help gather the SMTP log, you can refer to the suggestion
below:

First, enable SMTP log on your Default SMTP Virtual Server.

a. Please open Internet Services Manager.
b. Right click on "Default SMTP Virtual Server" and click Properties.
c. On the General tab, please check the option "Enable logging".
d. Select W3C Extended Log File Format from the list below.
e. Click the Properties button. In the General Properties tab, please
confirm the following settings:
- Check the option Daily
- Check the option "Use local time for file naming and rollover"
- Confirm the setting for "Log file directory" to be
"C:\WINNT\System32\LogFiles"
- Check all the logging options on the Advanced tab.

Second, reproduce the issue.
Third, send me the log file under C:\WINNT\System32\LogFiles\SMTPSVC#" (#
is a number. The number for the Default SMTP Virtual Server is 1). Also,
provide the sender recipient, and time. You can send the log file to my
mailbox v-chayan@xxxxxxxxxxxxx


1. Please also check the event log to see if there are any error events on
Exchange transports, please also paste it to newsgroup.
2. If you enable the message tracking, can you check where it stops? You
can check where the emails sent to? It should be important for us to
identify the issue. You can follow the steps below to enable message
tracking:

246856 How to enable message tracking in Exchange 2000 Server and in
Exchange
http://support.microsoft.com/?id=246856

I really appreciate your effort on this issue, please feel free to post
back your results. I will be here waiting for your updates.



Best regards,

| Dear Charles
|
| Thank you for your reply. In answer to your questions:
|
| 1. Is there any error event on the SBS event view, it should be some error
| log on the event view.
|
| There are no errors what so ever in the event log.
|
| 2. Do you have any problem when sending outbound emails to a self created
| distribution list with recipient less than 100?
|
| No - not that I am aware:
|
| 3. Is there any third party anti-spam software, please temporally remove
it
| to see if the issue can be resolved.
|
| No -there is no anti-spam software.
|
| 4. Where you create the distribution list, on your Exchange server or it
is
| a distribution list created by a remote mail server? If it is created by
the
| Exchange mail server, the number has been reached to limitation.
|
| We are not using distributions lists. I simply clicked on 'reply all' to
an
| email which had about 750 email addresses in the 'to' field. This resulted
| in me sending an email with 750 email addresses in the 'to' field. I know
| that there is nothing particulary wrong with this address list as I have
| recieved many emails from other people on the same address list who used
the
| same method to send the email.
|
| FYI I use use Outlook 2003 as my email client.
|
| 5. You had also to contact with your ISP to see if there are any
limitation
| on their side to send the emails to a large distribution list.
|
| I have checked with the ISP and there are no such limitations.
|
| We also have this same issue with one of our clients (we are an IT Support
| company). They also use MS Small Business Server 2003
|
| Thank you for your assistance.
|
| Best wishes
|
| Charlie Wetherall
