SURBL scored stronger than normal on the apache servers?

<snip> email containing the surbl permanent test point, and no spam quotes.

The test-point URL used to only be listed in SC, although tests at
uribl.com and rulesemporium.com both just report it as listed as a "test
point" and don't list out any SURBL sub-lists it belongs to. ...

So has apache.org jumped up their score, or is there some change in the
listing here that's causing SA deployments to go nuts on this test point?

21 points seems absolutely *absurd* for just SC, or any test point.

(Actually 21 seems a little bit out-of-whack for any combination of
rules all looking at the same small attribute of the email, no matter
how strong a spam sign it is, except perhaps an end-user configured
explicit blacklist.)

That at least explains the change.. It's also in some ways sensible in
that you can quickly see that all the SURBL checks are enabled.

Unfortunately it also means we can't even post messages to the list
containing the test point, which isn't so good, but I guess the same
goes for the GTUBE.

The test points were changed from returning a value of 127.0.0.2
to 127.0.0.126 as of about a year ago.  I neglected to announce
the change, though it was mentioned on the SURBL discussion list.
Announcing now.

127.0.0.126 represents all ones for the bits of all existing
lists.  This was a suggestion from one of the SpamAssassin
developers.
