All mail through NKS is filtered through our MailAssistants to tag spam,
block viruses, and otherwise pre-treat email for ourselves and our
customers (we quite happily eat our own dogfood ;) The SpamAssassin
score is but once piece in the overall weighting and identification of
potential spam.

The weighting threshold is 6, the message had a score of 11.488. The one
you are really questioning is the following default SpamAssassin rule:
# idea from Robert Menschel <RMSA@Menschel.net>
header FROM_HAS_MIXED_NUMS3 From:addr =~
/^[a-z]+\d+[a-z]+\d+[a-z]+\w*\@/i
describe FROM_HAS_MIXED_NUMS3 From: contains numbers mixed in
with letters
While this does add 3.25 to your potential score, it doesn't top a score
of 6 from this alone.
If you look closer, you will see the various RCVD_IN matches as well.
Apparently, your IP netblock is listed in various spam blacklists -
particularly the various public dialup lists. These lists are maintained
for transient IP blocks (typically DHCP blocks or PPP dialup banks) that
rotate through customers on an ongoing basis, causing much headache as
spammers come and go using those IP addresses.
Most of the weighting here is due to your ISP's netblock being
blacklisted on these lists.
