incoming/external email can not delivered to user mailbox

Dear SBS-ers,

Today I have a strange problem that some incoming/external email from
customer can not delivered to user mailbox.

When I track the messages via message tracking center, external
messages from the sender show the following:
==========
SMTP: Message Submitted to Advanced Queueing
SMTP: Started Message Submission to Advanced Queue
SMTP: Message Submitted to Categorizer
SMTP: Message Categorized and Queued for Routing
SMTP: Non Delivery Report (NDR) generated
==========

But still that email has not reach user mailbox yet. I also checked
via OWA. Pls help..

FYI : SBS SP1 with exchange SP2, MS IMF antispam on, GFI mail
security.
I've checked both in IMF and GFI, there is no such email in the
quarantine box.

Any responses appreciated.

The message generated an NDR, so it won't have been delivered. What was the
NDR the sender received? Ask them to forward it to you (to another address,
like Gmail/Hotmail/etc).

I think I have similar problem with this user:

Hi All,

I'm having this problem of being not able to send/recieve emails more
than 5mb. I'm running Exchange 2003 on Win2K3 server. I've set Global,
User, SMTP Virtual Server, connector message limit to 15360kb (15MB).
I test send a 7MB email and check the tracking center. Results as
below

SMTP: Message Submitted to Advance Queuing
SMTP: Started Message submission to Advanced Queue
SMTP: Message submitted to Categorizer
SMTP: Message Categorized and Queued for Routing
SMTP: Non-Delivered Report (NDR) Generated.

The NDR as below:

This message is larger than the current system limit or the
recipient's mailbox is full. Create a shorter message body or remove
attachments and try sending it again.
<mailer.XXXXXX.com #5.2.3>


The error from event viewer as below:


An error occurred while Microsoft Exchange Intelligent Message Filter
attempted to filter a message with ID
<D7E34616DB681A44B370531939630C233AC72E@server.domainname.com>, P1
From smtp:XXXXX@domainname.com and Subject FW: 7 mb. This message
will not be filtered. The error code is 0x800710f0.

Is there anyway to set the email limit to 15mb?

I think you've answered your own question :)

This is normal for the IMF filter - it "fails" on emails larger than
about 3Mb's. Don't worry about this error message.

Of course, see the user's ADUC for a change to this user only, or change
the default for everyone - the former might be better.

Even better, educate the user - all the users if you can. Email's not a
very good file transfer mechanism. Seems damn crazy to me to send 15+
Mb emails out! - doesn't it to you? Use a web file drop, or share
otherwise (is it internal to internal?).

Hi Risal,

Thanks for your post and Lanwench's input.

Due to lacking of enough information, like Lanwench said, please paste the
NDR letter so that we can see the reason why your SBS rejected the sender's
mail. I would also like to know that:

1. Does this issue only occur to certain external domain or all incoming
emails from external?

2. Have you tried add that email domain to your Global Accept List in IMF
if you are using Connection Filtering?


Based on the current situation, please try the following steps to collect
more information:

First, enable the Diagnostics Logging to Maximum.

Please try the steps in the following article to enable and set Diagnostics
Logging to Maximum for MSExchangeTransport services. Then send a test
email and after a while, check if there is any warning or error message
regards to this test email in Event log.

You may refer to the following article for detailed steps:

How to troubleshoot for Exchange Server 2003 transport issues
http://support.microsoft.com/kb/821910/en-us


Second, if the issue can be reproduced, please reproduce it by sending a
test email from the original same sender. If possible, we can involve the
original sender to help to finish our test to reproduce this issue.

Third, if it can be reproduced, please help me to collect the following
information:

Information Need
==============
1. On the SBS server, open event viewer, please help save the Application
and System log to *.evt , compress them and send to me at
v-robmen@microsoft.com
2. If possible, please capture some screenshot of the NDR letter and send
it to me : v-robmen@microsoft.com

Hope this helps. Also, if you have any questions or concerns, please do not
hesitate to let me know.

Thanks for your earlier feedback!



Best regards,
Robbin Meng(MSFT)

Hi Risal,

Glad to get your update.

If you are experiencing the exact NDR as indicated in the link you shared,
then it seems the sender is trying to send a large email that is bigger
than the size limit of your Exchange server.

Size limits for messages depend on various settings. Settings can vary
across users. You can customize the settings for the Exchange 2000 or
Exchange 2003 organization, a specific connector, a specific virtual
server, and an individual user.

For more information, please refer to KB322679

How to set size limits for messages in Exchange Server
http://support.microsoft.com/kb/322679/en-us

If the issue persists, please let me know whether the issue occurs to all
of your domain users or just some of them. Also, does this issue only occur
to certain external domain or all incoming emails from external?


Hope this helps. Also, if you have any questions or concerns, please do not
hesitate to let me know.

Thanks for your earlier feedback!

Thanks Robin. I have investigated about this problem and the fact is
the incoming mail is bigger than allowed policy and there is no NDR
generated from SBS because I disabled it ( prevoiuosly I have
unchecked Allow NDR report in message format section) so that customer
outside did not know whether email is receive or bounce.

To prevent this happen again, I have checked Allow NDR report so
there will be a notification rerport if email is not delivered.

Kind Regards,
Risal

Hi Risal,

Thanks for your feedback. I hope the information I provided could be of any
help.

I understand that the fact is the incoming mail is bigger than allowed
message restriction policy. It's all right to enable the Allow NDR report
so that the sender will get notification in case you miss any important
business emails.

If you have any other concern on this issue or need further assistance from
me, just let me know. Thank you for your time and cooperation.

Here are some SBS 2003 server articles just for your reference:
