Block <<unknown>> sender

Block <<unknown>> sender

Post by K.K » Thu, 03 May 2001 13:24:17



Dear all;

Few days ago some of the users' mailbox were attacked by infected message.  I tried to use the 'track message' function to find out who sent the message, I got the records but the sender is "<<unknown>>".  Does it means I have no way to find out where's the mail came from?

Is there any method to block out all the <<unknown>> sender?

Thanks.

Keith
