[horde] horde smtp auth ssl

[George]

Hi,

I could not find much info about this problem and what I found did not
solve mine.

I am trying to set up horde to send using smtp authentication and
tls/ssl. I could not see the option to set it via the administration
interface so I am trying it now directly in the horde config file. I
need to set the following settings:
$conf['mailer']['params']['host'] = 'smtps.somedomain.com';
$conf['mailer']['params']['port'] = 465;
$conf['mailer']['params']['localhost'] = 'smtps.somedomain.com';
$conf['mailer']['params']['auth'] = 'WHAT DO I USE HERE?'; (I have the
option PLAIN, LOGIN, MD5-something)
$conf['mailer']['params']['username'] = 'USERNAME';
$conf['mailer']['params']['password'] = 'PASSWORD';
$conf['mailer']['type'] = 'smtp';

For host I tried to use ssl://smtps.somedomain.com but it did not
help. Says it can't connect to smtp server. For auth I am not sure
what to use.

Please help

Thanks
