Who Sent That EmailDo you really know Who Sent That Email you are reading? Have you ever received a joke email message that looked like it came from Your favourite POP star, actor, actress or even the Queen. If you have then you will know just how easy it is to be fooled with email. The problem with Internet email is that it is basically insecure. You have in fact no way of knowing, under normal circumstances, that the email came from the purported sender.

Phishing attacks/scams are becoming more and more common, and it is not surprising given just how easy it is to pretend to be someone else. Therefore you should never trust that the Email your have just received actually came from the sender. So never give away any personal data in response to an email, and always treat links in an email with suspicion and if they are to a private site (bank, paypal etc) never use them. Putting Trust back into EmailBecause of the growth and the obvious danger in spam and phishing there are currently two initiative for putting trust back into email. They are Sender id (Microsoft) and Domain Keys (Yahoo). They are not widely implemented as yet and I will cover them in later articles. For personal email use between two business colleagues/friends email signatures have been available for many years and I will cover these in a future article.
