Just a heads up- Down stream customer and end-user spammer norcal-systems.net via layer9.net started spamming yesterday afternoon. At first I was going to dismiss this and wait till Monday, but the complaints came in at a constant and fast pace. So I placed a filter on their network t about 3:00pm EST yesterday. Extended IP access list 142 deny tcp 216.115.78.0 0.0.1.255 eq smtp any log (2226195 matches) permit ip any any (57747076 matches) What was really great is when I called layer9.net's provider, their Abuse guy suggested that we just null0 the offending block, but needs to get approval from his manager. Since its obvious this customer is going to get booted, make sure they don't find you! -r
