Ask Slashdot: Spoof an Email Bounce With Windows?

An anonymous reader writes "One cool feature I used on KMail years ago was the ability to generate a spoofed email bounce for any given message I had received, which claimed delivery failed because of an unknown recipient. While this doesn't exactly align with expected behaviour from a mail client, it was a useful way of easily getting off mailing lists (automated, or manually created by freaky acquaintances!). This is something I really miss, so I'm wondering if there are any mail clients for Windows that provide similar functionality?"

      Sure, go ahead... that's an easy answer, since the question started with "One cool feature I used on KMail years ago ...".

      Bounce has legit purposes. The only reason you don't see it in many other clients is the pompous philosophy that UI's should completely remove features that might cause any confusion to any one of the users. It's extremely simple to implement, so that's not why it isn't there. It's been in mail clients of old, so they have actively had to do something in order to remove it (it's lack of presence cost developer time, not used it). It's one of those things that should show up when someone selects the "show advanced options" checkbox, but that's not trendy.

      IMO, they should call up Redmond and find out what their recommended way of doing this is. If users don't ask for the features they want, how is the provider supposed to know their user base? Granted, I doubt there'd be enough requests to warrant adding "bounce" back to the main Outlook UI, but maybe there's a registry flag they could toggle? (again, why do people keep dropping the advanced options from the UI? Gnome/Unity/Ubuntu, I'm looking at you!)

He's talking about mailing lists owned or bought by companies and used to send completely legitimate emails to prospective customers; you can get on these when you give out your email address, or when you buy things online from various companies. You might only get emails from a company you bought from, or they may sell your email address and then you'll get emails from other companies you haven't bought from. Either way, it's actually legal AFAICT, until you opt-out. The problem is the opt-out process usually isn't that easy, by design.
