------------------------------------------------------------------------------
+ 2.5.2. Neutral
+
+ The domain owner has explicitly stated that he cannot or does not want to assert whether or not the IP address is authorized.
+ A "Neutral" result MUST be treated exactly like the "None" result; the distinction exists only for informational purposes.
+ Treating "Neutral" more harshly than "None" would discourage domain owners from testing the use of SPF records (see Section 9.1).

2.5.5. SoftFail
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.

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.

2.5.1. None
no records were published by the domain or no checkable sender domain could be determined from the given identity. The checking software cannot ascertain whether or not the client host is authorized.
