I use letsencrypt for my mail server and I have done so for years, but iOS 18 appears to have broken my configuration which has worked perfectly for as long as I can remember. I believe my certificates were all set up correctly because it never gave me a problem up until now and never asked for authorisation of any kind. At this stage MacOSX works just fine, but iOS 18 and iPadOS 18 just do nothing.
