Sorry, wrong diagnosis on my part. But correct about the
strength of your feeling. I will try to reassure you (that
our desires are very similar) in the following...

I completely understand this, and thoroughly agree with the
principle of delivery that you're referring to.
Perhaps I misled you by raising this while talking about
'temp' files. I would abhor any proposal to 'ack' the
client while mail could still be lost by a power-out.
That's not what I'm suggesting. If you still think my
proposal compromises integrity, I'll be interested to know
why.
As for having an option, that's a complete non-starter,
that means fattening ka9q, not slimming it.
But I'm not going to get steamed up about this. Now that I
know I can successfully receive a 900K mail, and that it
wasn't that one causing my problems earlier this week, I
find this discussion more academic. Whilst IMO it might
have been nice if ka9q had worked this way from the outset,
I can imagine resistance to risking extra support calls from
non-techie ka9q users upgrading. (Is that an oxymoron? Are
there non-techie ka9q users <g>).
Perhaps I find it easier to accept the concept of
post-processing mail offline because I already do precisely
that. Instead of using the .txt files as they stand, with
PcElm or similar, I invoke mail2snz within demon.bat.
This happens automatically, even if I have a power-out.
So an extra post-processor isn't a big conceptual leap for
me. The essence of what I'm asking is: "What's the
difference between 'ack'ing receipt of mail when it's safely
stored on your hard disk, or when it's safely stored on your
hard disk?". <straight face, but a little twinkle around
the eyes, so you know I didn't mistype the question :-) >

That's irrelevant, I think. Even if it's true. I've
never seen it stated as a principle, and I've certainly
had mail bounce where the report only included the
first few lines of my original (I agree that's inconvenient,
meant in some cases I had to go digging in my archive to
retrieve the whole original). Of course, those partial
reports may have come from non-conforming systems. <shrug>
