>>><br>
In the last days I'm getting a lot of image only spam.<br>
<br>
It contains no links and no text at all<br>
<br>
The size of the image is different every time, and it advertizes pharmacy
inviting users to visit funny sites with always different names like <a
href="http://www.8654.org">www.8654.org</a> and similar.<br>
<br>
I've palayed around spamassassin rules with some luck (somettimes I catch
sometimes I don't).<br>
<br>
Has anyone else seen something similar?<br>
<br>
Any ideas about how to stop it?<br>
<br>
Best regards and thanks<br>
<br>
