In and by itself, a "PASS" should not buy you anything. However, a "PASS"
becomes (is already) very important when used in combination with reputation
services, such as rating.cloudmark.com. I attach a whopping 2.5 SpamAssassin
score to domains of good reputation, for instance. But only, and ONLY, when
their relay is authorized. That is where SPF "PASS" comes in. :)
Why take the risk of getting my domain blacklisted.
It is particularly difficult, for small domains, to build up a good
reputation (mail volume way below threshold). I venture to say, conversely,
that getting blacklisted, for that same reason, is equally hard (not on a
local blacklist, per se; but yes, it should certainly be the case for global
reputation services). So, I would not worry about that too much.
