+
+### What kind of database are you using?
+None. No *sql database required.

+You'll probably want to `push` your config updates to your server and restart the container to apply changes.  
+
+### Where are emails stored?
+Mails are stored in `/var/mail/${domain}/${username}`.  
+You should use a data volume container for `/var/mail` for data persistence. Otherwise, your data may be lost.
+
+### How can I configure my email client?
+Login are full email address (`user@domain.com`).  
+Both login and password are managed in `postfix/accounts.cf` file.  
+Please have a look to the `README` in order to manage users and aliases.

+### How can I manage my custom Spamassassin rules?
+Antispam rules are managed in `spamassassin/rules.cf`.  
+
+### What kind of SSL certificates can I use?
+You can use the same certificates you use with another mail server.  
+The only thing is that we provide a `self-signed` certificate tool and a `letsencrypt` certificate loader.
