We are operating a server which already has DKIM + SPF applied on it. We have interspire software on this server. We give clients the ability to send mass emails from our servers, but first they have to apply SPF-DKIM changes to the sending domains. The problem we have is that although we are telling them to add our DKIM-SPF records on their domains, some of them forgot, others don't know how to do it, etc.
For all those that fail to comply with our policy, we want to force a change on the header of the email.
We are looking for someone that apply the following feature-logic on our server.
a. Check DKIM record for sending domain
b. Check SPF record for sending domain
c. if a or b failed, then rewrite sending domain to the default domain we will tell you and sign it with [url removed, login to view]'s DKIM.
Please be aware that we are using postfix and this cannot change!
