You understand that web servers (listening on a web server port) and mail servers (listening on one or more mail server ports, possibly on the same computer) are entirely different technologies?
Yes, it is, but it has become common practice in Germany to automatically portray things that the AfD also wants as "far-right demands". That is, of course, utter nonsense.
My point was meant differently than it may have sounded. Personally, as a German myself, I am open to leaving both the EU and the euro. I was only concerned with the implication that "Euro = EU", which is factually wrong.
Andorra, Monaco, San Marino and Vatican City have the euro, but are not in the EU; Bulgaria, the Czech Republic, Hungary, Poland, Romania and Sweden are in the EU, but do not yet have the euro. A special case is Denmark, which is currently the only EU country with a "non-participation option" that has decided not to introduce the euro in future either.
Linux is probably not the wisest choice for gaming - that would still be Windows. Anyway, the distribution does not matter that much. You can install most Linux and cross-platform software on most distributions. Do not choose your system because of what comes as the default desktop, default package set et cetera. Try a few ones. Read some reviews.
