SPAM that only has one or two URLs in it
Hi all,
Lately I've received few spam messages that did not have any text except one
or two links.
Some of them had an empty subject line. I guess they hope naive people
would click on the links just out of curiosity.
The scored few points but not enough to reject them.

So I was wondering how to write a rule that would specify that the body is
only a URL (or few URLs with spaces in between) ?
