check out the “virtualbox” guide on this site: https://itsfoss.com/install-linux-in-virtualbox/

it basically teaches you how to install/run linux inside a “simulated computer” on your computer, so you dont break anything important

seems to be decent and i couldnt spot any obvious errors in the guide

i usually rely on https://mxtoolbox.com/ for quick checks good overview about mail and dns related issues

fuck, half of my critical services think I am spam

that goes away after your dns gets older and your mailserver gets “reputation”… also configure your dmarc and dkim, that tends to help a lot

another reason could be that your public ip is “dirty”, check the reputation of it and maybe request a different one from your hoster

no you are confusing that with hatED which is the new redhat AI enabled text editor

because it can be fun, you emacs user :D

just like cheering for $sportsballteam

all i want it linux mint devuan edition

just remember redhat is also at fault for pulseaudio and systemd xD

i see it more like telling somebody to weightlift 50kg first instead of immediately going for 500kg

then you might be in over your head and shouldnt use what you are not able to use

yeah… not having an readily available admin-c will just lead to the domain and ip getting bad reputation in case there is the slightest issue
