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.

Actually, I think the risk of getting blacklisted for a small domain like
mine that is actively being used (forged) to send spam is rather greater
than my opportunities for whitelisting. I get more bounces due to forged
spam than I send legitimate e-mail, so it is safe to say that there is more
spam than ham that purports to be from my domain. Trying to avoid having
people believe that the spam is really from me (it's not) is why I'm here.
