This feature has been around since Mac OS X 10.0 and I was using it actively in every version of Mac OS X. It was one of the key reasons why I used Apple Mail instead of Web-Mail for my GMail, Yahoo!, and MobileMe accounts among others.
A lot of people mis-understand bounce mail as it were.
If a friend of mine has their address stolen or a virus infection on their system which is often the case when I use this feature, I want them to get bounce messages from me so they will call me and I, as a IT support person, can explain to them why they're getting bounced and to either clean up their system or remove me from their address book.
90% of the time when someone gets a Bounce and didn't send the email THIS is the case people. Windows users and Mac users alike should be using anti-virus software. Mac users ask themselves why? Think of it this way, do you want to spread previously infected files you received from others to other people that may not be using a Mac and thereby increasing a potential infection? I think not.
It's nice to know spam mail is on the decline. Unsolicited Commercial Email however may not be.
Every once in awhile it's a nice thing to be able to bounce to an ex-girlfriend ex-wife, ex-boyfriend, ex-husband, ex-employer, etc. For these instances the Bounce Message feature was consistent and worked well.
Don't mis-understand, there is no karma thing at play here, we're talkig about unsolicited email and spam for the most part. I have no problem bouncing it, I am using a computer with all the tools at my disposal. I read thousands of emails a week. If someone gives me effective tools like Postini and SpamSieve I use them. I even use Email accounts that have automated filtering systems behind them to help reduce and question the email that I receive to ensure it's from someone I care to get email from and that it was addressed directly to me in some fashion.
I honestly do not give a crap about anyone who generates spam and uce for a living whether they're in East Europe, Russia, Africa, or anywhere else. This is coming from someone who has on more than one occasion worked for national Internet Service Providers and now works for a large enterprise. The cost of spam is paid for by your internet fees and cell phone bills. Now that is not necessarily going to decrease when Spam decreases, however I paid for the connectivity and bandwidth for a reason and it's my choice on how I use it.
I would highly appreciate it if the tools that were previously provided in Apple Mail under Mac OS X 10.6, namely the Bounce Message feature were restored. It should be my choice to enable and use this feature for my own intentions. If Apple wants to improve it or give some ridiculous legal disclaimer fine, don't care. Just give me back the simple tool "that just works"
Thank you!
