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!
