If we go too quickly through triage of some issues, here are some others 
we can discuss:

G.5.  Remove or deprecate the work-around from code 552 to 452

    The suggestion in Section may have outlived its usefulness
    and/or be inconsistent with current practice.  Should it be removed
    and/or explicitly deprecated?

G.7.1.  Issues with 521, 554, and 556 codes

    See new Section  More text may be needed, there or
    elsewhere, about choices of codes in response to initial opening and
    to EHLO, especially to deal with selective policy rejections.
