Raises an interesting point with regard to CHUNKING. Why in
predata specifically?

  - I'll start with: you don't want it at RCPT or earlier
    because that will impact sender-verify callbacks.
    And you'd prefer before all the data is transmitted
    because that's a waste of bits and cpu.


    Any more?


What should be preferred practice
when CHUNKING is used?
