I get a non-deliverable report (with error codes 5.5.0 and 5.3.4 when I try and send a mail over about 10MB.
I've set limits at 100,000KB in each of 'Global settings', 'SMTP Connector settings', 'SMTP virtual server settings', and 'User mailbox settings'.
Exchange server message tracking shows the message being transferred outbound (and I can see the network connection is busy for several minutes as data is being transferred across to the internet connection), but then a non-delivered report (NDR) is generated.
I can't work out what is creating the NDR! Can anyone help?
