Windows 7: Bounce emails?

Can anyone recommend a good email bouncing program? I know it's not a good idea to bounce SPAM back to its originator since this can validate your email address for them. I just want to bounce some emails back to certain "friends". I have tried Bounce Buddy 1.0, but it doesn't seem to work too well on my Win 7 64-bit system. And I can't seem to get CoffeeCup SPAM Blocker to work right either. I mainly use Eudora 7 and Thunderbird for my emails, and have tried "Redirect" add-ons for Thunderbird, but they won't work with the version of Thunderbird that I am using.

Any suggestions? Any and all help appreciated...

Thanks!

Hi.

The Bounce Bully is old but good and compatible with windows 7,i dont use it anymore so i dont know if its good for your needs.

Mailwasher Free Spam Filter Software.

Have always in mind that "it's not always a good idea to bounce SPAM back to its originator since this can validate your email address for them"

As stated in my original post, Bounce Bully 1.0 doesn't work for me. I also tried MailWasher Pro and while I got it configured to properly download my mail, it would not bounce any of them...

I HAVE found a solution, though. Thanks for your suggestions!
