I received the same PM , however welcome back @Spekulatius. ( I hope you're not coming to use again GMX or web.de). I simple gmail address with the 2FA it's the better solution and obviously secure .
It is better when you have your own Mailserver

For example with autoban (Try it out on my Server if you want, try 2 times to login - then you get banned for 1 Year:
Admin@Dice-Win.com)
Best regards
It locks you out for a year after only 2 failed attempts?! How are you able to login when you are drunk?
