Ironport IEA - PXE Encryption failure

          Hi, we currently can't encrypt emails and receive the  message  below, have checked what I can (which is limited) but can't see anything obvious.

#< #5.0.0 smtp; 5.x.3 - PXE Encryption failure. (Message could not be encrypted due to a system configuration issue. Please contact your administrator.) (delivery attempts: 0)> #SMTP#

Can anyone point me in the right direction please?

IEA370, 6.5.5

Is this a snippet from the NDR? You should try to find the message in message tracking and see if you get more detail on the error. It could be due to size, was it a large message?

Thanks I've found it! The feature keys had run out in the ISA device, there were what looked like temporary ones that last for 28 days which I've applied and it all works, will sort out permanent ones now.

Thanks for responding
