Roundcube Community Forum

Hello all,

I'm testing a roundcube with virtualmin, and it breaks the string passed down on $config['smtp_server'].

IMAP work greats, only SMTP.

I will try to expose the most about my configuration and what troubleshoot i did.

I have a fully working roundcube whit this settings wihout virtualmin installed.

$config['default_host'] = array(
        'mailserver 1' => 'Webmail 1',
        'mailserver 2' => 'Webmail 2',
);

$config['mail_domain'] = '%d';
$config['smtp_server'] = 'mail.%t';
$config['smtp_port'] = '25';
$config['smtp_user'] = '%u';
$config['smtp_pass'] = '%p';
$config['smtp_auth_type'] = '';

Why this configuration, because i have two mail servers, and the authentication of the users is via user.domain instead user@domain.
What I'm doing here since I have clientes connecting to two different servers, is populating each client smtp server settings with mail.domain.


Now when I install a roundcube alongside virtualmin, all up to date, centos 7 x64 and try to send and email I get this error SMTP Error (-1): Connection to server failed.


So i think and still do it has to be with DNS, and that the named(BIND) service was the culprit so i disabled it.
Manually identified the nameservers in /etc/resolv.conf to Google and made sure that if i nslookup my mail server it resolved.

Now the strange thing begins to happen, if SMTP_SERVER is configured like this $config['smtp_server'] = 'mail.%t'; or %n or %t it always gives the SMTP ERROR(-1).

But if i configure directly with hostname or IP address I can send emails.

Here are the logs, about the error, noticed too that it points to rcube.php line 1648.

[02-Mar-2017 15:26:45 ERROR: Failed to connect socket: php_network_getaddresses: getaddrinfo failed: Name or service not known ()

Which points to this:
// log error
            if (!$sent) {
                self::raise_error(array('code' => 800, 'type' => 'smtp',
                    'line' => __LINE__, 'file' => __FILE__,
                    'message' => join("\n", $response)), true, false);




Here is the header from google, verifying my user has a permitted sender, which is the expected output.

Authentication-Results: mx.google.com;
       spf=pass (google.com: domain of ............... as permitted sender)


Please advise,

Thank you.

and what is the server name you are using? you do not have to say the exact one but the format of it so that we can see what %n and %t would resolve to.

for example if its webmail.mysite.com then %n = webmail.mysite.com and %t = mysite.com
