Send alert for size limit

Question

Our users occasionally receive emails with large attachments. I've set separate size limits for inbound and outbond emails, but I discovered that all inbound emails were being caught by the outbound limit when transferring within our server. Is there a way to send an alert to the intended recipient when this happens?

Answer 1

Nothing built-in, no. The sender will get notified of course

Answer 2

Hi @Nicholas94 ,
As Andy says, there is no built-in setting to send alerts to intended recipients.
Do you know whether the original sender received an NDR ?
As a workaround, you could refer to the following articles to forward the NDR to your postmaster.
