Hi there! I've installed ispConfig 18.104.22.168 an it's working great for me. Because I had to install it on an existing server environment I decided to take it step by step. The Webserver configuration worked fine and is up and running. Now it's time to move the email-stuff. Existing environment: - Postfixadmin is (still) in use - Spamassassin up & running - sieve up & running - Roundcube (v 0.52) - Plugins: - password - sieverules - sauserprefs - markasJunk2 1. Postfixadmin: This caused a major headache, but I was able to get the data from postfixadmin over to the ispconfig db. And here is my first question: Postfixadmin used md5 password encryption whereas ispconfig used something else. I've modified: /usr/local/ispconfig/interface/web/mail/form/mail_user.tform.php Modified Line 84: Encryption set to md5 My target is to preserve the user Passwords. What I want to do now is to reconfigure / reinstall ISPConfig but this time with a mailserver. Is there anything else to make the md5-encryption work? 2. Roundcube This is also a major problem. This is definitley caused by several features the users have in their webmailer (f.e. tag spam, setup filterrules within roundcube & stuff). Because this seems to be a hell lot of work to get this going I want to keep my current anti-spam & filtering solution in place and just use the user-administration of ispconfig. Therefore here is my second question: Is there a major problem with this by modifying the postfix-configuration (main.cf) after the reinstall of ISPConfig? (I thought about excluding clamAV as a transport-pipe.) The only thing that is still problematic is the feature that users are able to change their password from within the webmailer. I found the sql-command in the plugin-configuration file and wondered if it is possible to change this command, so it writes to the isp-db? The Anti-Spam stuff I'm going to migrate on another shiny day. ;-) I appreciate any suggestions.
