I have a rather complicated postfix setup that I'm needing some thoughts/input on how to accomplish.. (and what minimum version of Postfix I might need to use to get it done).
History / Existing infrastructure. So, we are selling Spam filtering / archiving email services through an external service called Reflexion. Basically their setup requires you to set them as the MX of your domain, and then have all originating mail go out through their sending server. This does two things.. First it allows them to archive the email (if we have that feature turned on for that customer) AND it removes the "control panel" that gets appended to incoming emails (e.g. spam control etc..) when an email is forwarded. As external users are not supposed to see that at all The current server uses sender_dependent_relayhost_maps to setup domain-based map of domains that use Reflexion to ensure originating mail gets sent out.. However that doesn't handle internal mail. (e.g. between users of the same domain or between users of two separate hosted domains). The current setup (CentOS 5 based-server) running postfix 2.3.3 The problem / new infrastructure. The problem of course is I need to find someway to get the internal mail forwarded out to Reflexion before coming back in. This further gets complicated as not all domains on the (existing) server use reflexion. The new server is a CentOS 6 64bit server.. Thus, postfix 2.6.6. (I can upgrade if needed) My initial thinking was to do something to the submission port (thus requiring all users to use SMTP submission to send email and NOT use port 25). To have it somehow use the auth to determine who should have their mail ran through reflexion instead. (auth is full emailaddress). Having "some" domains using reflexion and some not. can be removed a as a requirement if need be. Although it can complicate things if a customer adds the service as we now have to move them from one server to another. So, any thoughts on how to get Postfix configured to do this without creating loops. And hopefully handling all the internal mail complexities.. (e.g. hosted non-reflexion domain email -> hosted reflexion domain email, reflex->reflex domain and reflex->non-reflex domain).. And let me know what extra clarification is needed?
