I have managed to setup Bankoi webhost-panel (free) , it integrates with mailenable (standard), web based admin is no problem, Bankoi has webanalyzer Built in (free), webmail lacking from mailenable standard , I use UebiMiau (free web based email). This is basically a full controlpanel system all built from free or open sources for Windows server. Finally something that is all FREE for Windows. Those looking for free Windows controlpanel can try this.

Spam control via Black list with mailenable, only thing I still cant manage to integrate is virus scan for email. Maybe someone here can give a good suggestion?

Try ClamWin (http://clamwin.sourceforge.net). GPLed and Free.

Clamwin is good, but prob is how to integrate with mailenable standard edition : (

Refer to their Docs and configure the scanner to run (under MTA service) at arrival of every email with appropriate parameters.

Hope it could be of some help.
