Try this out for size, they are a few custom rules I have created myself. # Catch Image ONLY spams! rawbody __FVGT_rb_HTML_HAS_AHREF eval:html_tag_exists('a') rawbody __FVGT_rb_HTML_HAS_IMG eval:html_tag_exists('img') full __FVGT_rb_HTML_LEN_80_375 /<(?:html|body).{80,375}<\/(?:body|html)>/is full __FVGT_rb_A_THEN_IMG /<a.{12,155}<img/is meta FVGT_m_IMAGE_ONLY_SPAM (__FVGT_rb_HTML_LEN_80_375 && __FVGT_rb_HTML_HAS_AHREF && __FVGT_rb_HTML_HAS_IMG && __FVGT_rb_A_THEN_IMG) describe FVGT_m_IMAGE_ONLY_SPAM Short HTML message with IMG and A HREF score FVGT_m_IMAGE_ONLY_SPAM 3.5 The size of 80,375 might need to be tweaked but this rule does what you are looking for! ------------------------------------------------------- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.
