    Hello,

    I am unsure how a hacker can use my email in Envelope-to: and try to send spam and finally bounce that to Return-Path:

    Do we have any setting to tweak in exim to control or block or deny such emails?

    Below is the mail header of unknown bounce emails I receive.

    You could try sending an email from your domain name using a PHP script on another server. Send the message to a server with SPF verification enabled to see if it's correctly rejected.

    Thank you.
