I'd forgotten just how much of a pain in the arse it is to juggle all the configs for mail servers and all that shit.
So many things I'd set up, then expelled knowledge of from my brain, because I've not touched it in so long.
So here I am trying to stand up a newer version of the server this is -- currently -- being served from, as a migration from the legacy hosting platform.
It's going. I won't say it's going well, but it's going. Not helped by a wooly head from welding all day; but at least everything smells like rutile welding electrodes!
