And there's the wonderful thing about RFCs... this clause can be read in
different ways. Focussing on the "human user" element:

...which I took to mean "the person sending the mail can try to send it
again". This is not the same as treating a 5yz (permanent) result as a
4yz (transient) result, because transient results are designed to be
retried by the machines involved where permanent results require human
intervention to repeat the original command sequence - and even then
this is usually after they have changed something, so strictly speaking
it's *not* the original command sequence in those cases.
Perhaps I wasn't clear enough about that yesterday. In fact, I think
that clause isn't really clear about it in the first place, but the
"human user" part is the key IMO.
