Here's the second great advantage of this method: If an email cannot be delivered, you will be notified of this in your In Box almost immediately. If everybody you know does this then you need not ever worry about opening mail from friends.
This contact will then show up as your first contact.
If a virus attempts to do a “send all” on your contact list, your PC will pop up an error message saying that: “The Message could not be sent.
If this is happening, then you may notice missing, non-existent and/or incorrect entries.
