Yep. Sadly, the mail provider I use for personal email had a spam check to 
consider dates 2020 and later to be “from the future” and rejected mail. It 
took a few hours for them to fix it on 1/1, meanwhile, considerable mail was 
lost. Check your various spam checking processes.

As my mail provider has told me they updated it to 2030, I now have a reminder 
set on my computer for 1-Dec-2029 to remind them to update it (should I still 
be using them 10 years from now).
