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). -- Larry Stone lston...@stonejongleux.com <mailto:lston...@stonejongleux.com>
