-
- This should not be happening. The file delivery was attempted on should have
- been renamed so that it no longer appears at the front of the queue. PMDF sorts
- messages and attempts delivery on messages with the fewest delivery attempts
- first.
-
- Moreover, any subsequent immediate delivery jobs should not see this message at
- all no matter what its name is; it should be too old to be considered.
-
- I have no explanation other than to suggest you have seriously busted PMDF
- somehow.

-
- Someone has posted a message containing a bogus part; it is labelled as
- an NBS part but it is not. PMDF-MR has absolutely no interaction with
- any of this -- the part is purely a bag of bits.
-
- PMDF-MR has no choice but to offer these parts to Message Router; there is no
- way to check from for legality. And if they fail Message Router is placed in an
- inconsistent and unrecoverable state. The entire transaction has to be aborted.
- Experience has also shown that sometimes things will work on a subsequent
- attempt -- I have no idea why this happens, but it has been reported to occur.
- (I have never been able to duplicate it locally; they are either legal or
- illegal in any test I've done.)
-
- It is therefore impossible to do anything other than what PMDF-MR is doing now;
- the message should eventually time out and bounce, and in the meantime it
- should not block the queue in any way.
