I don't want to receive emails from a certain email address anymore, but I want to keep my email address. So I hope there is a way to somehow reply (automatically or otherwise) to emails from that address with an "undeliverable" reply that looks like it is coming from the mailer daemon as if my email address doesn't exist anymore.

Any ideas?

If you don't care about mail spoofing set (and if it is allowed) then set your sender to and send something like this back (or just send using your address, depending of how technically versed the intended recipient is)

This is the mail system at host

I'm sorry to have to inform you that your message could not
be delivered to one or more recipients.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can
delete your own text from the attached returned message.

                   The mail system

<>: unknown user: "your.address"

Reporting-MTA: dns; your.mail.server
X-Postfix-Queue-ID: 7C5A8244352
X-Postfix-Sender: rfc822; root@your.mail.server

Final-Recipient: rfc822;
Action: failed
Status: 5.1.1
Diagnostic-Code: X-Postfix; unknown user: ""

That should be more or less clear (and frightening).

Note that if the receiving party is a little smart they will find out that this is a scam ;-)

Oh, and don't send anything back to spammers. Just make them believe you're dead.
