All (legitimate) MTAs should be able to deal with transient failure, period.
The fact is that they don't.
Moving your transient failure indication after the end of DATA certainly
isn't a panacea for broken MTAs.
Not only that but I don't even think that moving there would give any
overall benefit versus tempfailing before DATA.
Indeed I have heard tell that some (broken) MTAs ignore errors after the
end of DATA.
