Authentication Error

[CarlosinFL]

I've got RC installed and working great with Postfix, Dovecot, Apache, & PostgreSQL however when I try and send, I get a pink error on the RC page that says:

SMTP Error 250: Authentication Error

I'm logged in and can receive & read all new and old messages via IMAP however when I compose and or reply to an older message is when I get the error above. I watched the logs on my mail server to see if I can get more info about what's failing when I try and send but the /var/log/mail.log shows only me logging in with a successful TLS session and nothing more. What I am doing wrong and or missing? :confused:

Enable imap_debug and post the log here.

[alec]

This is SMTP error, so enable smtp_debug and post thge log here

[SKaero]

I'm to use to typing imap, sorry about that!

[CarlosinFL]

I have not done the SMTP debug yet but just from basic troubleshooting, I think I know what the problem is. My mail server is rejecting my web server from sending mail due to 'relay access denied':

Now the above was my web server on the same network / same subnet trying to access my mail server.

mail - 192.168.1.200 / 211.113.101.135
www - 192.168.1.201 / 211.113.101.136

Above addresses are internal IP / external static IP.

However when I look in my mail server logs, I see:

OK so I fixed the DNS issue above but sadly that did not change anything. I enabled smtp_debug on Postfix just for the IP that roundcube was installed and requesting from <192.168.0.201> and below is what I got:

[CarlosinFL]

Can anyone help me understand this? I don't understand why and I think it's related to the main.inc.php file. This has to be an issue specific to RC only because when I install Thunderbird on the same server as RC, it works fine.

[alec]

Your server requires TLS connection. So, add tls:// prefix in smtp_server config option in Roundcube.

[CarlosinFL]

I did. Here are my SMTP parameters in main.inc.php:

Code Select Expand

$rcmail_config['smtp_server'] = 'tls://mail.domain.tld';

$rcmail_config['smtp_port'] = 25;

$rcmail_config['smtp_user'] = '%u';

$rcmail_config['smtp_pass'] = '%p';

$rcmail_config['smtp_auth_type'] = '';

$rcmail_config['smtp_auth_cid'] = null;

$rcmail_config['smtp_auth_pw'] = null;

$rcmail_config['smtp_helo_host'] = '';

$rcmail_config['smtp_timeout'] = 0;
Maybe someone else's eyes will see what I am missing. I've tried 'tls://192.168.0.201' & 'tls://mail.domain.tld'.

What PHP version? What Roundcube version? Do you have openssl module for PHP enabled?

[CarlosinFL]

What PHP version? What Roundcube version? Do you have openssl module for PHP enabled?

PHP5 - 5.3.3-6
RoundCube - 0.5 Beta
OpenSSL - 0.9.8o-4

I don't know if the openssl module for PHP is enabled but I checked in '/etc/php5/apache2/php.ini' & didn't find anything match when I search for 'openssl'. I would be very worried if the installer check let me proceed if I was missing requirements. When I did the install, it said everything was met and working fine.

[CarlosinFL]

When I tried to send, I checked the RC logs and here's what I have:

[21-Dec-2010 15:05:46 -0500]: SMTP Error: SMTP error: Authentication failure: SMTP server does not support authentication (Code: ) in /var/www/webmail/program/steps/mail/func.inc on line 1515 (POST /webmail/?_unlock=loading1292961946080?_task=mail&_action=send)
Here is what I have in main.inc.php:

Code Select Expand

// SMTP AUTH type (DIGEST-MD5, CRAM-MD5, LOGIN, PLAIN or empty to use
// best server supported one)
$rcmail_config['smtp_auth_type'] = 'PLAIN';

I don't know if I need the 'XXX' between the entry or what? Some have them in the config and others don't. Very confusing. My SMTP isn't using SASL, just TLS.

Openssl is an optional module, but you need it. Run Installer again and check if you have this module installed (you can do this also by executing `php -m` command)

I'm assuming this is on my web server where RC is installed and not my mail server which only has Postfix / Dovecot installed and nothing more, right?

[alec]

Right, you can install php-openssl module on http server or disable TLS on postfix.
