I have a legacy application that emails via php.
5% of the emails aren't going through. The solution is to route all email through a fancy verified mail server like Amazon's SES. I am having some trouble implementing this functionality.
It seems this guy had a similar problem.
My question is where in postfix can I set a filter that will take as input the the message headers, so that I can manually set the
From field and the
Reply-To field to
email@example.com, respectively. Where whatever_php_wants is dictated by the php program and the users registration email.
I know where to set the noreply portion, but I don't know the exact place in postfix's configuration files where I can intercept complete emails and pass them to a script.
So I want emails to look like:
FROM: firstname.lastname@example.org REPLY-TO: the_users_address@their_email_service.com
