I imagine it would only be useful against ethical spammers. There is no such thing.
Those spamming lists of "guaranteed" addresses won't remove bad addresses because then they have fewer to sell. Plus, they don't care. Those buying the lists generally don't care either, and/or don't know how to remove NDRed addresses. Those spamming other products that are illegal or dubious almost always use invalid return addresses. The NDRs would wind up going to /dev/null or to someone who the spammers have decided to screw over. I'd look at another approach. -- be - MOS If you ever fall off the Sears Tower, just go real limp, because maybe you'll look like a dummy and people will try to catch you because, hey, free dummy. > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] > Sent: Thursday, January 10, 2002 2:37 PM > To: Exchange Discussions > Subject: Different kind of spam fighter > > > Somewhere in the back of my brain, I remember seeing a tool > that you could > run on received spam that would simulate a NDR back to the sender, > pretending that the email address was invalid. > > Does anyone know of such a tool and how effective it might or > might not be? > > > Mitch Claborn - Ignite Sales > (972) 458-5519 > [EMAIL PROTECTED] > _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
