Error 554

[rinzes]

When I attempt to send email I get the following error:

SMTP Error (554): Failed to add recipient "xxxxxx@gmail.com" (5.7.1 <localhost[127.0.0.1]>: Client host rejected: Access denied).

error log:

[08-Sep-2015 10:52:06 -0400]: SMTP Error: SMTP error: Failed to add recipient 'xxxxxx@gmail.com' in /usr/share/roundcube/program/include/rcmail.php on line 1035 (POST /roundcube/?_unlock=loading1441723924933&_lang=en?_task=mail&_action=send)

Any and all help would be appreciated

Did you configure Roundcube to use SMTP server with authentication? See smtp_* options in config.

Yes I did..  I have the following:

$rcmail_config['smtp_server'] = 'ssl://localhost';
$rcmail_config['smtp_port'] = 465;
$rcmail_config['smtp_user'] = '';
$rcmail_config['smtp_pass'] = '';
$rcmail_config['smtp_auth_type'] = '';

[alec]

No, you didn't

Please enlighten me then

$rcmail_config['smtp_user'] = '';
$rcmail_config['smtp_pass'] = '';

right here, these settings mean do not use smtp authentication.

I found the problem. It was in my /etc/postfix/master.cf file It's now working ok
