Server
The server I work on almost every day.
The use cases:
website hoster
Mostly hosted with apache, php 7, mysql 8 and node js. Also let's encrypt for my ssl certificates
Virtual private network
Openvpn with it's own dns server. The dns server is configured as an caching server, meaning that the result of each dns query is saved. This boost my online privacy, as other dns server like of your isp can't link the dns queries and my ip-adress.
Email-server
Postfix and dovecote. This is just the best way to avoid spam.
