I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

check with your spam provider on a particular example attachment. spam filters often take mails apart and reconstruct them in different forms and sizes and then deliver them to you a larger file size.

If you are trying to send an email out of your organization check also the relative send connector max size

I'm not sure if you are the sender or recipient, but the NDR you attached shows that he recipient side rejected the mail because of the size. So if you are the sender, the recipient side is rejecting the mail. This is something the recipient will need to address. Please confirm if you are the sender or recipient.

Ciao timgreen, good point.
Reading the headers, I assume the OP is the sender (From: header contains Barry) and that the email did not leave his organization.
So i believe he has size restriction on send connector.

please run the following cmdlets to see the size limits in your environment

Check global Transport
get-transportconfig | ft maxsendsize, maxreceivesize

Check all Receive Connectors
get-receiveconnector | ft name, maxmessagesize

Check all Send Connectors
get-sendconnector | ft name, maxmessagesize


If the sizes are above 14MB then the issue is your the recipient side or your smart host if your are using one.

Sorry for the ambiguity guys. I am sending into a domain that I administer. I will check the smart host size limits, that could very well be the problem.
