Kaijanen.net / Tuomas

Vaihdoin kaijanen.net palvelinalustan Windowssista Linuxiin ja siinä samalla siivoilin vanhemmat palvelimella viipyilleet html pohjaiset sivut bittien taivaaseen. Harrasteautoille ei nyt oikein riitä enää aikaa, ja noille sivuille kohdistui muutenkin vain hyvin harvoin liikennettä.

After upgrading Roundcube to 0.2.1 and after that to 0.2.2 TLS was broken again. Actually TSL was not working between my mail server and Roundcube before that either, but at least I could keep TSL on in the mail server.

I am running Roundcube and my mail server in the same machine, so the fact that traffic between Roundcube and my mail server was not encrypted is not a problem. Unfortunately with 0.2.1 and 0.2.2 I had to turn the TSL support completely off in order to get Roundcube functioning. When TSL turned on my Roundcube installation could not send mails, and from the logs could be seen the following errors:

[22-May-2009 ] STARTTLS failed ():
[22-May-2009 ] Invalid response code received from server (-1):

Solution was to downgrade NET_SMTP to version 1.3.1 http://pear.php.net/package/Net_SMTP/download/1.3.1

In “Roundcube installation path”\program\lib\net  replace the SMTP.php with the version from Net_SMTP 1.3.1 release.

I have been using RoundCube (http://roundcube.net/) in my home server for a while. Installing and configuring RoundCube has been quite an easy task before (even though I am running it with Windows 2008 server and IIS7).

But when the 0.2-stable version was released I did run into a problem that took a while to solve. Sending e-mails when TLS was enabled in my mailserver did not work. RoundCube did just hang with this error in log.

[03-Jan-2009 09:44:51] Unable to find the socket transport "ssl" - did you
forget to enable it when you configured PHP? (5): 

After googling a while I found an article that stated that openssl.dll and sockedts.dll should be
enabled in php.ini : 

extension=php_openssl.dll
extension=php_sockets.dll

Also in RoundCube main.inc.php it is adviced to add "ssl://" to mailserver settings

// use this host for sending mails.
// to use SSL connection, set ssl://smtp.host.com
// if left blank, the PHP mail() function is used
$rcmail_config['smtp_server'] = 'ssl://localhost';

But in my case sending e-mails only functions if the mailserver settings are without  "ssl://"

// use this host for sending mails.
// to use SSL connection, set ssl://smtp.host.com
// if left blank, the PHP mail() function is used
$rcmail_config['smtp_server'] = 'localhost';

With these changes the RoundCube is now functioning as it used to.
