Horde SMTP instead of Sendmail

[majidA]

I want to set horde to use smtp instead of sendmail.
I change this parameters in /usr/share/psa-horde/config/conf.php

/*$conf['mailer']['params']['sendmail_path'] = '/usr/sbin/sendmail';*/
/*$conf['mailer']['params']['sendmail_args'] = '-oi';*/
$conf['mailer']['type'] = 'smtp';
$config['mailer']['params']['host'] = 'localhost';
$conf['mailer']['params']['auth'] = '0';

but this error appears when i send mail to destination@domain.com via horde:

There was an error sending your message: Failed to add recipient: # destination@domain.com [SMTP: Invalid response code received from server (code: 553, response: sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1))]

resolved my problem by this setting:

$conf['mailer']['params']['sendmail_path'] = '/var/qmail/bin/sendmail';
$conf['mailer']['params']['sendmail_args'] = '-oi';
$conf['mailer']['type'] = 'smtp';
$conf['mailer']['params']['port'] = 587;
$conf['mailer']['params']['auth'] = true;
