I am using Microsoft Outlook 2000 as email client and MDaemon as mailserver...... Almost daily to one of the account i received around 30-40 emails which are spam. Although i am using Norton AntiSpam 2004. Interestingly there is no sender's address and even the receiver address No subject no contents. Seems to be harmless but it may not be..... Any guess what it could be and where the hell are they.... Are they from outside the network or from inside the network.
