With the Update of Plesk Panel to version 10.x there may be some problems with the solution in my <a href="http://www.roundcubeforum.net/general-discussion/5034-how-install-roundcube-plesk.html" target="_blank">first post</a>.<ol class="decimal"><li>Please prepare Roundcube as described in my <a href="http://www.roundcubeforum.net/general-discussion/5034-how-install-roundcube-plesk.html" target="_blank">post</a></li><li>Rename file called <strong><strong>/var/www/atmail/</strong>index.html</strong> to <strong><strong>/var/www/atmail/</strong>index.html.org</strong></li><li>Rename file called <strong><strong>/var/www/atmail/</strong>index.php</strong> to <strong><strong>/var/www/atmail/</strong>index.php.org</strong></li><li>Create a new file <strong><strong><strong>/var/www/atmail/</strong></strong>index.php</strong>:<br>
PHP Code:
<?php<br>
<br>
/** <br>
* Setup here your URI to your Roundcube installation <br>
* <br>
* Example 1: <br>
* $roundcube = 'http://webmail.yourserver.com/'; <br>
* Example 2: <br>
* $roundcube = 'http://yourserver.com/webmail/'; <br>
*/ <br>
$roundcube = 'http://yourserver.com/webmail/'; <br>
<br>
header('Location: ' . $roundcube); <br>
exit(); <br>
<br>
?>
</li><li>If you have a domain name:<br>
Then make a new folder in your <strong>/var/www/vhosts/yourserver.com/httpdocs</strong> of the domain called <strong>webmail </strong>and copy all files and directories from Roundcube folder into it.<br>
If you want webmail.yourdomain.com instead of youserver.com/webmail/ please make a new subdomain called webmail and link it into the folder /var/www/vhosts/yourserver.com/httpdocs/webmail.</li></ol>This should work on Plesk 10.x (perhabs on older versions to) and with Roundcube versions 0.3.x and newer.<br>
I've tried to use the new feature in Plesk Planel 10.x to set an own thirdparty webmail. But without any chance to get it worked. So, please use the solution I've described here. The other solution with Horde is more difficult and makes more problems, since Plesk version 10.x.
