The spam is always from mstiffanij () netzero com The IPs are always Verizon DSL IPs 71.107.XXX.XXX A number of people have responded with "Why don't you block them"... I have blocked them, that's not the problem. The bigger issue is that Verizon refuses to take action or even let me talk to anybody in the security department... their support department claims to not even have a phone number to reach anybody in security. I have the resources in place to prevent the attacks, I'm just tired of seeing the same spammer show up with a count of 5,000 attempts every single day. I have had similar incidents with other major providers such as SBC, at least they're eventually responsive. But Verizon refuses to cooperate. ----- Original Message ----- From: "Michael T Pins" <mtpins () nndev org> To: <incidents () securityfocus com> Sent: Thursday, July 07, 2005 6:29 PM Subject: Re: Constant spam from Verizon.net

only recourse.Define "a specific e-mail address linked to several Verizon DSL IP addresses." If all the email is originating from just a few DSL IP addresses, just add those IPs to your access list (assuming you're running sendmail). If not, you'll need to be rather more specific as to what's going on. Yes, this is a bandage on the symptom rather than a solution to the real problem, but until you can convince someone at Verizon to cut those IPs off, it will at least stop the spam. -- Michael T Pins | "Major combat operations have ended." mtpins () nndev org | - George W.
