OtC,
If you're suspicious about an apparently safe official e-mail do a right-click on the title and left-click properties. You can see the headers without opening the message. Always assuming that, if you're using Outlook Express, you haven't allowed the message to be opened in the "Viewing Pane". This option should be unchecked in the View>Layout menu.
Often, the e-mail that purports to come from a respected source can be seen to have come from a domain that you have never heard of before.
And there's a new trick afoot. It used to be safe if you got an e-mail from eBay asking you to go to Site with a URL starting with http
s. Well, today an obviously spam e-mail coming from !eBay contained an https URL.
But I binned it anyway.
It's been a bad few days for viruses and spam, but the new BT/Yahoo setup is coping with the problems well. But they will keep changing things... Oh dear, I am getting old.
