undeliverable message size same as the original sending message?
Hi all, We are going to inplement sending size of messages to every one. What's the better way to do this?(exchange 2003) I just tested it out and got undeliverable message(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. with the same attachment size that I sent. Can we make the undelivable message smaller or not including original attachment? Thank you.

GReat and I followed the link and created the key and restart SMTP. Now, I got "The attachment size exceeds the allowable limit" when I send large than limit attachment in outlook, Is this supposed to be as I do not get any undeliverable message any more? Thank you.

Yes. If you enable this option, you can save server and network resources. However, there are drawbacks to this implementation of Simple Mail Transfer Protocol (SMTP) attachment stripping. If you enable this option to strip the attachments from the non-delivery report (NDR), the details that are necessary to display the notification in the preview pane are also stripped, and the originator of the message cannot use the Send Again option.James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

It's worse than that. By limiting the size of the messages attached to the NDR you instruct Exchange to simply chop off the rest of the message in excess of the limit. If the attached message was MIME then the closing MIME delimiter disappears and the message is no longer in an acceptable format and it may be discarded by other mail systems that (quite reasonably) expect inbound e-mail to be correctly formed MIME. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

So, in practice, it's better to leave the NDR with attachments (some attachmetns could be very big)??? We only limit sending size which only applies to our company users. That's why we do not want users to receive NDR with the original attachemnts .. Thank you.

This is actually a very old issue, what Exchange 2003 SP level are you on and what Outlook version and SP? Exchange 2003 SP2 with Outlook 2003 SP2 would've prevented the message from being sent in the first place.James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

Thank you for your follow up. We arer at exchange 2003 SP2 and outlook 2007 SP2. I have another thread http://social.technet.microsoft.com/Forums/en-US/exchangesvradmin/thread/1c05ded1-8261-4459-b587-a81d56853dea and I got "message size exceeds outgoing message size limit" immediately when I try to attach the attachment in outlook 2003 SP2. I did not receive any undeliverable message as notification 1 in that link thread Could outlook 2003 SP3 and outlook 2007 SP2 handle differently with sending message size limit set? Thank you.

No it shouldn't since versions are higher. When you got the NDR with attachment, was that client in cached mode?James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

I just tested with outlook 2003 and I still get undeliverable notification. >>When you got the NDR with attachment, was that client in cached mode? Probably at that time. Now, since I have added registry key to strip off attachment with NDR as the link suggested. I can not verify it now. Just wonder whether this is right?: we got the undeliverable message plus the the message you tried to send is in the send items folder too. Also, I have seperate exchange 2003 SP2 server and tested and I got "message size exceeds outgoing message size limit" immediately when I try to attach the attachment in outlook 2003 SP2. It stops me sending larger message than limit and certainly it's not in the sent items folder. This is good. I really do not know why two systems has different notifications outcome? Thank you

On your separate exchange 2003 SP2 that prevents you from sending larger messages than the limit, put the user in cached mode and see if the NDR comes back with the attachment.James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

>On your separate exchange 2003 SP2 that prevents you from sending larger messages than the limit, put the user in cached mode and see if the NDR comes back with the attachment. I did put the cached mode and I got "the attachment exceeds the allowable limit" when I tried to send larger messages than the limit and no change whether it's cached or not. This is totally different from another system which I received the undeliverable message which is (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. I still can not figure out why two different outcomes on two exchange 2003 SP2 servers? different exchange updates? Thank you.

I tested more on the system which I got the undeliverable messages. Whether I enabled or disabled outlook cache mode, I got ""the attachment exceeds the allowable limit" now when I tried to send larger messages than the limit. BTW, when I did this test, I only enabled the sending size limit on my account, will notification be different than the global sending size limit? I have no clue why this works now. I got this "the attachment exceeds the allowable limit" notification is because I enabled MaxDSNSize according to this http://support.microsoft.com/kb/555231 or the notification message should be " "the attachment exceeds the allowable limit" when we set the global sending size limit? Thank you for your great help.

If your server advertises ESMTP and the sender uses ESMTP then you should never accept a message that's too big (at least in an ideal world). >We only limit sending size which only applies to our company users.
