Hello Postfix users, I made a relatively comprehensive tutorial[1] on how to set up a mail server (Postfix, Dovecot, Rspamd,..) and integrate it with Nextcloud. My goal was to create a all-in-one, step-by-step tutorial from beginning to end.
I partly used other tutorials as a basis, but also did a lot of research and e.g. used much stricter smtpd_*_restrictions than I have seen anywhere else. It's a hobby project, I am not a full-time mail admin, so probably not useful for large companies. I would greatly appreciate your feedback and hints on possible errors or oversights.
