crontab -r … now i always look on the keyboard when i want to edit my cronjobs

very nice! Is there a button to hear the whole mixtape as a playlist, one after the other? Havent found a button for this.

No, its not safe, you wont hear incoming dangers. But these Noise Canceling Headphones have a nice feature for cities: with their microphones they can give you an „ambient sound“ feature. It mixes the noise from the outside to your music, so you can hear the surroundings while listening to music.

so what else is a factor for reputation? Or is it like if you dont pay to get your mail-domain whitelisted we lower your reputation score?

ip-reputation is also important. Mailgun, an email service for mass mailing, is doing an „ip-warmup“ if you choose a dedicated ip. So, if you are self-hosting with dynamic-ip, i think you would have a very very low ip-reputation.
