Thank you both for your comments.

Thankfully it is not me who has received the offending mail/s, but the webmaster in Australia, so it may have originated from down there as that is where the site is hosted. He rang me this morning to warn me.

That is the reason I wrote on the BB.. just in case anyone received any.I am well and truly protected with antivirus and firewall protection and only use web based emails anyway.
