if you need more reliability you can always use a second mailserver as backup, add a second mx record to your domain and if the first one is not responding the second one will be used. there is no limit of how many next servers there can be specified afaik.

have mine running for nearly 20 years now and never had any major issues with delivery 🤷

still steam prevents you from running more than one game at once from one account. can’t start vampire survivors on the deck and play manor lords on the other pc using the same account. family sharing and using multiple accounts should work, though 🤔

because it changes every 6 months and everyone get’s a turn

you can just set your pihole as the dns server for all your wireguard clients i guess

Postgeheimnis does not apply in some circunstances

we use it to classify data that is needed to be sent to one of three endpoints. chatgpt tells our tool where it belongs. there are.probably more practical ways to do this, but the customer wanted AI in his product so here we are 🤷

some do work, but not fullscreen restricted to the passenger side of the screen

i self host my mails for almost 20 years now, it was hard work in the beginning, now it’s just a few updates a year. no problem with blacklists or anything, a good hoster is probably beneficial, 10/10 would recommend, even just to learn how all of this works
