Getting back to a working, properly functioning installation that's secure, prevents spam, blocks spam, has AV, and uses DK and SPF correctly is like an act of God but possible. If there's a need I might be willing to develop a guide to do this at least for my OS distro. I'm currently running a fully up-to-date installation of 9.2.2. Everything is working exactly like it should including the MTA with SpamDyke support add-on.
I'd like to thank AtomicRocketTurtle Forums, the almost impossible KB here at Parallels, Google, and my wife for leaving me alone for almost 10 hours to get this back online. I can't tell you how nice it is to have a fully functioning MTA again.
