Thanks for all your observations...

Larry, thanks for you comment - the first thing I did when I became aware of this problem was to change my password - in fact, I make a habit of changing my passwords fairly regularly.....

I've received quite a bunch of emails to the affected address, designated as 'Undeliverable' and having examined the headers of these emails, I find that many of the addressees are no longer in my address book! In particular, there are two of our late 'KN' friends included - Fran Durham and Chuck Piper - both of whom died quite a long time ago. Their email addresses were removed from my list years ago, so I can only assume that the IDIOT who originated these emails, must have harvested all the addresses a long time ago and for some inconceivable reason, has just decided to inflict this rubbish on us. One wonders at the mindset of sad people like this, who have nothing better to do than propagate potentially harmful emails to all and sundry. What kind of 'kick' do they get out of doing so ??? Most internet users nowadays, are sufficiently 'savvy' not to be taken in by these stupid emails and generally just dump them, so what is the point?
