Unfortunately, Microsoft do have a fairly large spam problem -- not on the
corporate sites, but from places like spaces live com, livefilestore com, and
hotmail.com. It's currently number 7 on Spamhaus' "World's Worst Spam Service
ISPs" (http://www.spamhaus.org/statistics/networks.lasso).

The problem for URIBL_SBL is that it looks up the nameservers' IP addresses,
and Microsoft use the same nameservers for the main corporate sites and the
infested service-provider sites.

In this case, it looks like a valid listing for live com, but what is actually
listed is ns5 msft net, which is also a nameserver for asp net.

So either Microsoft needs to rearrange its nameservers so its spammy
service-provider operations don't affect the reputation of its corporate sites
(the ideal answer, but good luck persuading them of that), or Spamhaus needs to
stop listing Microsoft sites even though they're currently a major problem (not
likely, and certainly not ideal), or Spamhaus needs to come up with a
traditional URIBL which lists domain names as an alternative way of listing
particular problematic sites.

Or SpamAssassin can special-case the blighters, or we can live with Microsoft
incompetence making their product names look like spam signs.

(In any case, I received no response last time I queried a Spamhaus listing,
presumably because I was neither an ISP representative nor an ISP customer).
