Basic system administration:

• Can you login to the database db1 with username user1 ?
  
• Has user1 enough rights in database db1?
  
• Check in the db.inc.php the line starting with $rcmail_config['db_dsnw']. Does it have the right database, password and user name:

$rcmail_config['db_dsnw'] = 'pgsql://user1:password@localhost/db1';
