I’m still sometimes baffled about what I can do when I set my mind to it. The email server is back up and running as well as it was before. Oddly enough this was fixed basically by overwriting what was already there from a default install with backups. I used Meld on my Mint desktop to connect in and compare files in the live RHEL vs the legacy Fedora that it replaced. I’m still not sure how it all comes together but even the TLS is working. Now I can get around to moving the users to a DB so things like changing passwords will work properly. Still need to speed up WP but I’ve got leads and am working on it.
