What kind of database are you using?
None. No *sql database required.
This image is based on config files that can be versioned.
You'll probably want to push your config updates to your server and restart the container to apply changes.

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.

Antispam rules are managed in spamassassin/rules.cf.

You can use the same certificates you use with another mail server.

What about backups?
Backups
Assuming that you use docker-compose and a data volume container named maildata, you can backup your user mails like this:
docker run --rm \
--volumes-from maildata_1 \
-v "$(pwd)":/backups \
-ti tvial/docker-mailserver \
tar cvzf /backups/docker-mailserver-`date +%y%m%d-%H%M%S`.tgz /var/mail
