How To - Bounce/Return spam to sender in .NETHi,
I've spent a fair bit of time searching the internet for an example on how to bounce an email, like what MailWasher does from .NET. My home email server gets hit pretty badly with spam, and rather than using server software and risk losing email, i'd rather have some control over what gets deleted and bounced, and so forth. I've written a program that allows me to delete emails without downloading them, but can someone point me in the direction (either RFC or example) in any language (.NET, VB, Win32, etc). Would massivly appreciate it, ultimatley I want to write an app I can operate remotely etc, bust just need to work out how to bounce correctly. Thanks!

In most cases, the
sender's address is a real address that has been hijacked, so you will wind up sending your spam to them. In addition, if the spam does go back to the sender, you are, in effect, letting them know that your email address (which will be in the FROM field of your bounced email) is a real and valid address, so they will just send you more spam. Just get a good spam filter.

Note you could still deliver the email to the user even though you rejected it with an SMTP error. Once your email server has told the other server it took the email, any further action on your part would be an "abuse report" of sorts, and equally ineffective. You'll note that whenever you send an e-mail that gets bounced (Destination mailbox full, for example), the return notice you receive comes from your mailserver and not the recipient's. That's because the recipient responded to your e-mail with an error (3xx, 4xx, 5xx) and never accepted responsibility for delivery.
