Hi, I have Exchange 2007. Our client sent us an email and it was bounced back due to a large attachment (more than 10 MB). We didn't know they tried to send the email and they didn't get the bounced back message somehow. thus we were waiting for the email and they didn't know it didn't go through. I want to know if there is a way to get notification when my Exchange server bounces sender's email? Please advise! Thanks, Gracegrace

You should be able to get that information by parsing the smtp logs, but if it's rejected for exceeding an Organizational limit, and rejected at the boundary without being accepted. I don't know of anywhere else that would be recorded.[string](0..33|%{[char][int](46+("686552495351636652556262185355647068516270555358646562655775 0645570").substring(($_*2),2))})-replace " "

Thank you for your reply. Yes, their email was rejected due to exceeding the mail size limit. My hope is to receive the notification automatically, not by parsing log manually. Please advise if there is such way. Thanks,grace

You can automate parsing the log file and sending notifications based on finding events, but I don't know of any kind of event driven notification that you can enable with a checkbox somewhere.[string](0..33|%{[char][int](46+("686552495351636652556262185355647068516270555358646562655775 0645570").substring(($_*2),2))})-replace " "

You can try "The first example in the following code shows how to configure the Exchange 2007 organization to forward all DSN messages that have the DSN codes 5.7.1, 5.7.2, and 5.7.3 to the postmaster e-mail account."

Hi James, If I want to send the notification to administrator@mydomain.com, how the command will be? Please advice! There is no email account specified in "Set-TransportConfig -GenerateCopyOfDsnFor 5.7.1,5.7.2,5.7.3". Thanks, Gracegrace

Thank you for your reply. Yes, their email was rejected due to exceeding the mail size limit. My hope is to receive the notification automatically, not by parsing log manually. Please advise if there is such way. Thanks, grace Not for oversized messages. Your Exchange server never accepted the message because it was too big. Their mail server should have generated the NDR back to the original sender, not yours. Having said that, some 3rd party SMTP gateways allow you to create rules that will notify recipients when a message is rejected because its too large. I dont know of anything built in to Exchange for that.

Oversight, yes Andy is correct your server will not generate the NDR, it'll tell their mail server size is too big and their server sends back the ndr.James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

Hi, As per my knowledge, when emails exceed the max limits, the senders will receive NDR but Exchange administrators will not. For the demands, it can’t be configured in the Exchange server and client and it need some coding. And you will get more if you post it to Exchange Development forum: http://social.technet.microsoft.com/Forums/en-US/exchangesvrdevelopment/threads Hope this helps. ThanksSophia Xu
