A friend of mine has forwarded me an email tonight, ostensibly from me, with a very dodgy looking link in it.
A quick glance at the email reveals that although my name is right on the email, the email address isn't - the ISP is wrong and the one in question, TelkomSA.net, I have never used. So it wouldn't pass my spam filtering, which dumps all emails not in my address book into a separate folder.
Almost all emails from me will use btinternet.com as an ISP, btopenworld.com or me.com on rare occasions.
Be on your guard and if you see anything dodgy in my name, please LMK!
