[tutorial]: Your own mail server (Dovecot, Postfix, Rspamd) with tight Nextcloud (on Apache) integration for Debian

Hi all, hi @PancakeConnaisseur ! This tutorial is awesome, very detailed and everything is explained very well. But I have one issue with it. I’m using environment where we have MariaDB(MySQL) already deployed. I don’t want to install additional database instance just to maintain email addresses.

I was never working with PostgreSQL and it seems MySQL lacks some features like for example user-defined domain…

Can anybody help translating these SQL statements to MySQL?

Thank you so much.
