I had already renamed the file.
// spamassassin database settings
$rcmail_config['sauserprefs_db_dsnw'] = 'mysql://username:password@localhost/database';
Am I changing this with the info in mySQL database file for the email?
// PEAR database DSN for read only operations (if empty write database will be used)
// useful for database replication
$rcmail_config['sauserprefs_db_dsnr'] = '';
I'm not sure what this is. Can I leave it as is?
// table that holds user prefs
$rcmail_config['sauserprefs_sql_table_name'] = "userpref";
Is this the info I would find in the MySQL file for the email account? Or do I leave as is? And the rest of the file, are there changes I need to make or are these the default settings for the plugin?
