Greetings, All!

I've got an email server set up with Postfix and Dovecot, but Dovecot can't find any users. I'd ilke to use the database I set up in MariaDB for users (referenced by Postfix), but I'm just not sure how to do it. There's a line in dovecot.conf specifying /etc/dovecot/passwd.db, but obviously that's not the one I set up in MariaDB. Is what I want even possible? What distribution and version of Dovecot to do you use? I don't myself use the SQL support of it. But on Debian there's /etc/dovecot/dovecot-sql.conf.ext to configure it. You can find the docs about the SQL passdb/userdb support here:

https://doc.dovecot.org/configuration_manual/authentication/sql/#authenticat... I should have included that information the first time; forgive me for being negligent.  I'm using Ubuntu Server 18.04 LTS, and Dovecot is version 2.2.33.2.  I'll take a look at the link you provided.  Thanks!

I'm getting an error message saying "user unknown" when I send test emails to my server.  I'd bet folding money the reason is Dovecot isn't finding the MariaDB database that holds the email users, addresses, passwords, and aliases.  Can someone help me figure this out?  I can share the conf files and database particulars if necessary.

Here's what I see:

And here's the output from dovecot -n:

I hope someone can explain to me just what protocol I should be using to access a MariaDB database.

This line right here looks to be the problem. Do you have mysql support compiled into your Dovecot instance? I run my own domain and I thought I'd do SQL (mysql or sqllite) for my stuff, but the compilications were so much that it was simpler to drop to plain text files.

IMHO, if you have less than 500 users, just got flat files to start.

But back to your case, did you install the 'dovecot-mysql' package with your distribution? For debian, I search with:

 apt-cache search dovecot | grep mys

Okay, I checked, and dovecot-mysql is installed.  I can't see why that driver is unknown!

The driver is called "sql". See

Are you sure?  I looked at that page, and it says there are different drivers for MySQL and PostgreSQL:  mysql and pgsql respectively.  I also checked dovecot.conf, and there the driver is called "sql."

There is some ambiguity in the setting names, however:

In the "upper" authentication config file (possibly conf.d/auth-sql.conf.ext) you define which "internal" driver the authentication system will use. These are...more of a top-level engine selection if you will - perhaps not what you'd consider a "true" driver.

In the "lower" authentication config file (like dovecot-sql.conf.ext), which is referenced by the 'args' setting in the userdb & passdb sections of the "upper" file, is where you explicitly specific the "true" driver, the actual database, and any field mappings.

If you're just getting things setup I suggest you check out:

http://postfixadmin.sourceforge.net/

Very clean & simple admin GUI for mail services. It includes documentation for setting up Dovecot.

SQL is the **authentication** database, which has mysql **driver**. So in dovecot.conf you use sql, and in the config file for the sql authentication, you specify the driver. See https://github.com/dovecot/core/blob/master/doc/example-config/dovecot-sql.c...
