The Ultimate Annoying Email Deflector Shield

The Ultimate Annoying Email Deflector Shield

Marketers. Exes. Bosses who somehow got ahold of your personal email address. Sure, you could make a filter or click ‘report spam’ (as if that actually does anything…), but wouldn’t it be better if they just stopped emailing you altogether?

Oh, they will now. Check this trick out:

Have you ever emailed someone and gotten that “Delivery Permanently Failed” bounceback from some mailer-daemon? Here’s how to make the daemon (whatever the hell it is) work for you.

Here’s how you do it:
1. Hit Reply.
2. Edit the subject line by adding the words DELIVERY FAILURE: ahead of the original.
3. At the top of the body, simply paste in the quoted text below.
4. Enjoy your life.

We’ve taken the liberty of scrambling all of those numbers, server names and such, so none of the above is traceable. We’ve also deleted any reference to dates or email addresses so it can be used by anybody at any time. Yes, a very savvy IT professional will probably see through it. The other 99.95 per cent of the population will think your email address no longer works and probably won’t send you anything again. You win.

Let us know in the comments how you plan on using this. And if you ever email us and get something like this back, well, uh… gotta go! Bye!
