ZPanel has a graphical admin interface which enables email administrators to easily setup email forwarding per user and per domain.  However, the open-source community version of iRedAdmin panel interface does not contain this same capability.  Only the iRedAdmin Pro version enables administrators to setup email forwarding.

iRedMail and ZPanel each utilize the Postfix email service.  Consequently, if both use a MySql database as their back-end to store user email configurations, then each of their MySql database table structures will be quite similar.  Certain fields of the database tables may be a bit dissimilar.

In order to manually configure an email address to forward all received email (and leave a copy of the email on the server) you must use PhpMyAdmin to edit email box records within the ‘goto’ field of the ‘alias’ table of the ‘vmail’ database.

Example — Before Editing the Record:

address field value — user@maildomain.com
goto field value — user@maildomain.com

Example — After Editing the Record to Provide Forwarding:

address field value — user@maildomain.com
goto field value — user@fwd-domain.com,user@maildomain.com

Notice that the email address where you will forward the email is inserted as the first address in the ‘goto’ field, followed by a comma, and followed by the original email box address.  This configuration keeps each received email in the original mailbox (user@maildomain.com) on the server and forwards a copy of it to the forwarding email address (user@fwd-domain.com).

Install xRDP on Ubuntu 12.04

Open a terminal window CTRL+ALT+T

sudo apt-get install xrdp (enter)
answer Y(es) when promted

After installing xRDP, make sure Ubuntu xRDP is listening on Tcp Port 3389. Somehow it proxies to 5210. Enter this at the terminal:

netstat -an | grep “LISTEN ” | grep “:3389”

Make sure that your router is port forwarding TCP port 3389 to the lan IP of your Ubuntu.

From Windows 7, click Start, Programs, Accessories, and select Remote Desktop Connection. Enter the router public IP or fully qualified Hostname.DomainName.com of your Ubuntu server. No username or password is necessary at this point. Click connect.

You should go past the windows warning to allow desktop connection.

At the Screen that says Login to xrdp, Make sure the module in the dropdown list is sesman-Xvnc. Enter your username or root, enter your password, and click OK.

You should connect.

If you only achieve a desktop background, without side or top Ubuntu desktop menu items, then you may need to install Ubuntu gnome session fallback or somehow make 2d the default for xRDP connections rather than Unity 3d.

So, if you have a problem connecting, run the commands below and restart Ubuntu, and try connecting again.

echo “gnome-session –session=ubuntu-2d” > ~/.xsession

Or install gnome session fallback.

sudo apt-get install gnome-session-fallback
