Sigh, tried to use iRedAdmin as my mail server setup as it’s simple and works.
Sadly, I forgot it prefers a clean server, and it’s insistence on using Nginx is a bit of a pain. So have restored the pre-install snapshot.
So, no email for now, but I have saved all the old ones from the old server (now binned) and I only really used the Raithtech domain for twitter notifications, so no massive rush….
