You better all download and install 7.0alpha9 as it does contain significant changes & enhancements to email including qpsmtp & virus scanning (with basic on/off selection), spam filtering (with sensitivity, tagging, junkmail filtering & rejection level settings) and executable content message rejection (virus infected message rejection) all in a nice server manger panel.
Not the identical feature set of Jespers/Damians av panel but a worthwhile start, maybe it could be enhanced, probably the ability to remove quarantined & problem messages would be good.
I have installed 7.0alpha9 on an old box, a PII 233MHz with 90MB RAM & 3.2Gb HDD, which is sufficient for testing, if not a speed demon.
Look out for a bug that stops it rebooting the first time (until you apply the bug fix listed at sourceforge)
