Email Soft Bounce?

n079614

I'm testing email messages sent to a mail box that I know is currently full.

A mail message that I sent (with a mail client - not via EasyLink) received the following email response:

Action: failed
Status: 5.2.2
Diagnostic-Code: smtp;554-5.2.2 mailbox full

When I query the EasyLink system, I receive the following:

              <Events>

                <ArrivalEvent>

                  <ArrivalTime>2012-10-08T03:43:00.000Z</ArrivalTime>

                  <Class>5</Class>

                  <Subject>2</Subject>

                  <Detail>2</Detail>

                </ArrivalEvent>

              </Events>

It's my understanding that Class 5 is a permanent error and the delivery won't be retried.  I expected that this would have been a "soft bounce" and that the system would continue to retry delivery.

The jobs numbers are usme-94618680 and usme-94620234.

Our system just passes back what is returned to us by the downstream ISP of the recepient. It has no knowledge of the state of the recipients mailbox.

The "sent" status only signifies that we were able to send the message to the recipient ISP. The retry mechanism only applies to that step of the delivery. Once we successfully pass the message off (or exhaust our first-step retries), we will not attempt any further delivery, regardless of what DSN information we may receive.
