Thinking again (new day, more coffee):  Let's say I'm the
spammer and care shit about my account and other users.  Then I
could replace <http://www.xyzzy.claranet.de/> by a traditional
<http://home.de.clara.net/xyzzy/>.  And I could replace the
host by its IP <>.  That could hit
another <>.  OTOH, why should "user"
mention this kind of URL with an IP in his mail ?  Even if he
doesn't like <http://www.user.claranet.de> for obscure reasons
he could still use the URL <http://home.de.clara.net/user> or
<http://home.claranet.de/user> instead of an IP.

And I as spammer would know that users don't like IPs in URLs,
I'd use a double redirection like <http://xyzzy.webhop.info/>.
Abusing the IP makes no sense, neither directly nor as joe job.
