Does SPF Really Help Curtail Forged Email Headers? 90

Intelopment asks: "My Domain name has recently been used a lot in the 'Reply' field by some inconsiderate spammer, and my ISP has suggested that I consider using the Open SPF service as a way to stop spammers from using my domain name for in their mail headers field. From what I can tell, it requires the receiving mail server to actually participate in the SPF service, which is where I have my doubts. Does anyone have any experience with this service? Does it work? Are many ISPs using Open SFP?"

A Whitelist for Phone Calls? 151

javacowboy asks: "I've been getting lots of strange phone calls lately. Most of the time, my phone would ring less than three times and then stop before I can answer. Then, a couple of nights ago, I got a call at 3am in the morning. It had stopped ringing by the time I woke up. *69 revealed a number with an area code of 632, which does not exist. I called the number, and the call would not complete past the area code. I want a product or service with which I can set up a -whitelist- of numbers that I allow to make my phone ring. Any number not on the list, or an unlisted phone number, tries to call me, and the phone doesn't ring at all. I would pay as much for this service as I would pay to have my number removed from the phone directory. Is something like this possible? If so, how would I do it?"

Is There Any Reason to Report Spammers to ISPs? 117

marko_ramius asks: "For years I've been a good netizen and reported spam that I get to the appropriate contacts at various ISPs. In the entire time that I've done this I've gotten (maybe) 5 or 6 responses from those ISPs informing me that they have taken action against the spammer. In recent years however, I haven't gotten any responses. Are the ISP's so overwhelmed with abuse reports that they aren't able to respond to the spam reports? Do they even bother acting on said reports? Is there any real reason to report spammers?"

Spam-Bot Intrusion Caught — Now What? 76

An anonymous reader wonders: "I've recently detected and halted an intrusion on my home computer, taken some actions to prevent further intrusions, and located the software that was running a bot agent. Cursory examination showed that the bot software is intended for acting as an agent for spamming. Configuration files distinctly point at the user/host/domain of several bot-herders — damning evidence. Nothing would please me more than to see this botnet to be caught and disassembled, I'm sure much of the internet-using community would support this. Thanks in advance for your suggestions. So, to whom should I disclose this information for appropriate investigation, follow up, and countermeasures? "
