To enable SMTP Auth, you will need to modify the config.php file locate in /config/config.php line 50

Windows location with plesk . C:\Inetpub\vhosts\webmail\horde\config

Change the following line
$conf[‘mailer’][‘params’][‘auth’] = ‘0’;

to
$conf[‘mailer’][‘params’][‘auth’] = true;

**I recommend forcing everyone to authenticate when relaying email from your server. This includes php, asp mailer scripts
