Catch all great for spamhunters
Wednesday, February 28th, 2007I get one piece of advice over and over:
Make up a new e-mail address every time you have to register at a new service, or even post on someone else’s blog. Then you can just turn off that e-mail address if it ever gets harvested by a spammer.
That’s bad advice for regular people for one very good reason: To make it work, you’ll need to configure your domain as catch all. No matter what you put in front of the @, it’ll end up in your inbox, until the day you “turn that particular address off”. One day you’ll wake up to in excess of (wildly estimated) five thousand mails in your inbox, because a spammer decided to misuse your domain as the from address, or decided to do a dictionary attack - sending mail to thousands of made up addresses on your domain while trying to find valid ones. Also, turning off an address may not be all that easy unless you know a thing or two about the mail setup you’re using.
But it’s a very good idea if you’re a spamhunter, and live for tracking down people who sell their e-mail lists, or whose databases get hacked or whatever.
Pascal Van Hecke found out that Performancing.com’s database somehow ended up in the hands of a spammer. His findings were confirmed by another user.
