A bit further up in the roundcube config file there's a line defining
the database connection. The username, password and database name are
all in the definition - something like

 $config['db_dsnw'] = 'mysql://username:password at
host/database';

Thanks!!

I ran the query.  Got something like this

+---------------------------+-------------------------+
|    username                     |       mail_host               |
+---------------------------+-------------------------+
|     tdukes                          |        localhost                |
+---------------------------|-------------------------+

Can't say that's what I expected.? What about "getent hosts
127.0.0.1"?

Also, uncomment the ::1 line in /etc/hosts.

Can you share the specific output of the command?? It might help. From 
what you've told us, localhost resolves to the IPv6 local address, and 
that address is present on your "lo" device.? You *should* be able to 
connect.? The type of error might indicate what is still wrong with the 
system.
