citando a RFC4408:

2.5.5.  SoftFail

    A "SoftFail" result should be treated as somewhere between a "Fail"
    and a "Neutral".  The domain believes the host is not authorized but
    is not willing to make that strong of a statement.  Receiving
    software SHOULD NOT reject the message based solely on this result,
    but MAY subject the message to closer scrutiny than normal.

    The domain owner wants to discourage the use of this host and thus
    desires limited feedback when a "SoftFail" result occurs.  For
    example, the recipient's Mail User Agent (MUA) could highlight the
    "SoftFail" status, or the receiving MTA could give the sender a
    message using a technique called "greylisting" whereby the MTA can
    issue an SMTP reply code of 451 (4.3.0 DSN code) with a note the
    first time the message is received, but accept it the second time.
