Why does this hit __HAS_ANY_URI

[Ned Slider]

Hi all,

The following email hits __HAS_ANY_URI and I'm not sure why:
http://pastebin.com/jvFrFhA4

When I run the message through SpamAssassin in debug mode I see:

dbg: rules: __DOS_HAS_ANY_URI merged duplicates: __HAS_ANY_URI
dbg: rules: ran uri rule __DOS_HAS_ANY_URI ======> got hit: "r"

SpamAssassin version 3.3.2

Any clues? I'm guessing it has something to do with the email address in 
the message body?

Thanks.
