Noob problem with relay outgoing mail through ISP

Hello guys,

I pretty new on setting up webservices and i only have basic (CCNA 1º module) knowledge on networks :rolleyes:, and i am trying to set one web service on a local server, to receive and send mail through an mail server hosted in my ISP.

Setup:
- OSX
- Roundcubemail
- Server app
- Dinamic IP with No-IP link

Here is my default.inc.php:

Quote:

/ ----------------------------------
// SMTP
// ----------------------------------

// SMTP server host (for sending mails).
// To use SSL/TLS connection, enter hostname with prefix ssl:// or tls://
// If left blank, the PHP mail() function is used
// Supported replacement variables:
// %h - user's IMAP hostname
// %n - hostname ($_SERVER['SERVER_NAME'])
// %t - hostname without the first part
// %d - domain (http hostname $_SERVER['HTTP_HOST'] without the first part)
// %z - IMAP domain (IMAP hostname without the first part)
// For example %n = mail.domain.tld, %t = domain.tld

$config['smtp_server'] = ‘%n’;
// $config['smtp_server'] = ‘’;

// SMTP port (default is 25; use 587 for STARTTLS or 465 for the
// deprecated SSL over SMTP (aka SMTPS))

$config['smtp_port'] = 25;

// SMTP username (if required) if you use %u as the username Roundcube
// will use the current username for login

$config['smtp_user'] = '%u';
// $config['smtp_user'] = '';

// SMTP password (if required) if you use %p as the password Roundcube
// will use the current user's password for login

$config['smtp_pass'] = '%p';
// $config['smtp_pass'] = '';

// SMTP AUTH type (DIGEST-MD5, CRAM-MD5, LOGIN, PLAIN or empty to use
// best server supported one)

$config['smtp_auth_type'] = ‘LOGIN’;
// $config['smtp_auth_type'] = ‘’;

// Optional SMTP authentication identifier to be used as authorization proxy
$config['smtp_auth_cid'] = null;

// Optional SMTP authentication password to be used for smtp_auth_cid
$config['smtp_auth_pw'] = null;

// SMTP HELO host
// Hostname to give to the remote server for SMTP 'HELO' or 'EHLO' messages
// Leave this blank and you will get the server variable 'server_name' or
// localhost if that isn't defined.
$config['smtp_helo_host'] = '';

// SMTP connection timeout, in seconds. Default: 0 (use default_socket_timeout)
// Note: There's a known issue where using ssl connection with
// timeout > 0 causes connection errors (https://bugs.php.net/bug.php?id=54511)
$config['smtp_timeout'] = 0;

// SMTP socket context options
// See http://php.net/manual/en/context.ssl.php
// The example below enables server certificate validation, and
// requires 'smtp_timeout' to be non zero.
// $config['smtp_conn_options'] = array(
// 'ssl' => array(
// 'verify_peer' => true,
// 'verify_depth' => 3,
// 'cafile' => '/etc/openssl/certs/ca.crt',
// ),
// );
$config['smtp_conn_options'] = null;

And i am getting a:

Quote:

SMTP Error (250): Authentication failed.

Without being possible to send mails to no one.

And If i change those to default:

Quote:

$config['smtp_server'] = ‘’;
$config['smtp_port'] = 25;
$config['smtp_user'] = '';
$config['smtp_pass'] = '';
$config['smtp_auth_type'] = ‘’;

I would have a different output, here i am able to send and receive mails between my several domains in my ISP, but i am unable to send mails to domains such as gmail.com, receiving the following error:

Quote:

SMTP Error (550): Failed to add recipient "XXX" (Please turn on SMTP Authentication in your mail client.
XXX (XXX.local) [XXX]:XXX
is not permitted to relay through this server without authentication.).

I discover that SMTP works with authentication through SPF but i dont know how to set it up in my local server and/or my cpanel in my ISP :confused:

Mailservers don't allow you to send emails to outside domains/mailservers without authentication; otherwise it would be an open relay!

Authenticate using PHPMailer or similar. Example below:

$mailServerType = 'smtp';
$smtp_server = 'example.mymailcheap.com';
$smtp_user = 'user1@example.com';
$smtp_pw = 'UserPassword';
$smtp_port = 587;
$smtp_security = 'tls';

Thank you mailcheap.

Do i need to create a dedicated script for it? because i think it should authenticate through default.inc.php (as you can see above) =/

Do i need some kind of key to sign my mails? I have read a lot of stuff from SPF and DKIM but i dont know if that is the problem,or if i can solve it with that, and if yes how can i do it.

UPDATE1:

I have activated a smtp log:

UPDATE2:

I have people in this network working with outlook, and they use their creds both to SMTP and IMAP :-\ Now i am almost 100% that the problem must be from my local server.

UPDATE3:

It seems that i have bypass those errors, but still i am not receiving any mails in the outside email account, i am just able to send mails inside of my ISP. What i have done was playing with mail server link, this was the set:

config.inc.php:

Quote:

// ----------------------------------
// IMAP
// ----------------------------------
// The mail host chosen to perform the log-in.
// Leave blank to show a textbox at login, give a list of hosts
// to display a pulldown menu or set one host as string.

// Supported replacement variables:
// %n - hostname ($_SERVER['SERVER_NAME'])
// %t - hostname without the first part
// %d - domain (http hostname $_SERVER['HTTP_HOST'] without the first part)
// %s - domain name after the '@' from e-mail address provided at login screen
// For example %n = mail.domain.tld, %t = domain.tld
// WARNING: After hostname change update of mail_host column in users table is
// required to match old user data records with the new host.
$config['default_host'] = 'mail.X.pt';

(...)

// ----------------------------------

// %d - domain (http hostname $_SERVER['HTTP_HOST'] without the first part)
// %z - IMAP domain (IMAP hostname without the first part)
// For example %n = mail.domain.tld, %t = domain.tld

$config['smtp_server'] = ‘%h’;

defaults.inc.php:

$config['smtp_server'] = ‘%h’;

I FINALLY found what was doing this, it was my server app, i had to leave Mail turned on but without any relay outgoing mail through ISP activated, and i could not leave Mail turned off. :D
