If the application sets both to the same value, you may be able to use the 'sender_canonical_maps' feature to rewrite the envelope sender to an address that is local; http://www.postfix.org/postconf.5.html#sender_canonical_maps However, if the user of the application that sends the e-mail has control over the 'From:' address, they may reset it to a value that your workaround does not account for. So the preferred solution is to resolve this problem in the application itself, or at the next 'layer' within your application stack. For example, if the application uses PHP, you can force an envelope sender like this; sendmail_path = /usr/sbin/sendmail.postfix -t -i -r bounce.addr...@server.domain.tld Where 'server.domain.tld' is your local server, and 'bounce.address' is a working, local account on that server. The application may still specify its own header values, but it will not be able to override the envelope sender, and bounces return to you. Cya, Jona
