No, that's working as designed. The Programming Reference manual says "An
attempt to put a message on a queue that
already contains MaxQDepth messages fails with reason code MQRC_Q_FULL."
But once the application has received the 2053, it can then do whatever it
wants with the message (actuall, it's a potential message at this point).
The receiver channel program chooses to put the message to the DLQ, after
it maybe does some retrying. A user-written application can do something
different. From what I've seen, these apps generally fail.
It's probably clearer if you don't think of this as a sending app doing
delivery. The application program is really just another app writing to a
local queue - the transmit queue in this case. It's the channel that is the
sending app. It's set up to act as you say regarding the DLQ, but it isn't
running.

I recently had a customer transmission queue fill up because there receiver
channel was down. Because I am in Atlanta Ga. and they are in Germany, it
takes time to resolve such issues.
But, I was surprised that once the transmit queue was full, messages were
not placed on the dead letter queue. The sending application was just
failing with a 2053. The queue manager dose have a default dead letter
queue defined, and that queue does exist (SYSTEM.DEAD.LETTER.QUEUE). I have
always believed that if a message cannot be delivered for any reason it
goes to the dead letter queue if one is defined. Is that true?
