Hi Wietse, thanks a lot for your replies.
I've integrated a custom vacation script (similar to the famous vacation.pl which comes with postfixadmin). So users can enable vacation/atoreply in roundcube for example, once they check vacation/autoreply an new alias is created inside aliases with a special domain suffix so when postfix tries to send emails to users a this "special domain suffix" then a new transport is used which finally triggers this custom vacation.pl script. The thing is i enabled reject_authenticated_sender_login_mismatch so the script needs to authenticate using the credentials as the recipient as the user logged into Postfix needs to match the from header in the email. So the options are the ones you exposed above: Send autoreply emails through sendmail binary. Login using the same credentials as the from headers. Or login with some autoreply user and use these account in the from headers. By now i was looking for a way to send email using as credentials the ones in the from headers.
