I have an SMTP application that handle mailing lists and it use postfix relay to send emails to end users. For some emails sent to some groups, the "return-path" header is set to "from" header instead of "reply-to"
I want my users receive the bounces only to "reply to" address. Is it something I can handle at postfix end. I want to rewrite the "return-to" path in each mail to the value found in "reply-to"
