I'm using a custom root server to handle multiple domains on one IP. The basic OS is Debian and the WWW is done with: Nginx+MariaDB.
Now I'm trying to install any working non MySQL based Email service on it. I've watched several tutorials and googled the whole web for a solution. My last attempt was to work with Postfix and Dovecot. The emails was kind of identified but getting the error:
<domain.org/info@mail.domain.com> (expanded from <info@domain.org>):
mail for mail.domain.com loops back to myself
Is there a step by step explanation for multidomain mail alias setting that is not running on any MySQL?
Do I need to run my virtual emails on MySQL?
Any Cpanel or Plesk like interface that could handle virtual Email aliases on non MySQL basis?
