Did your MUA turn that into a clickable link?
Thunderbird yes
Evolution no
GMail yes
Squirrelmail no
Roundcubemail no
To me this says that SpamAssassin should see it as a URL and check the
domain when doing URBL testing. Especially if Outlook and/or Outlook
Express parse it as a URL. But only if clicking on the hot link in the
MUA results in a browser actually going to the site. In other words, if
it is useful to spammers to get people to go the URL then we should
recognize it s a URL.
The following examples are not correct, but it demonstrates the problem:
ASCII without decoding the domain sent as UTF-8

ASCII without decoding the domain sent as ISO-2022-JP
http://$BF|K\8l(B.$B%F%9%H(B/
My Thunderbird only interprets the first one completely as a URL string,
the second one it ends at the pipe character, making it useless for a
spammer. The first one is clickable, but I don't see that Firefox, at
least, is interpreting it as the proper domain. Except that I don't
understand the encodings enough to say what it is doing.
Can you show me the equivalent for the following URL, which is a real
site? That way we can easily answer the question "If the MUA makes it a
hot link, is it a link that works?"
