I re-sent the email and attachments at 19.24 30 Oct, and at the same time sent myself a plain test note and another with attachments. Neither has arrived so I assume you haven't had them either.
I've sent a further two tests to myself but they have disappeared too. Copies of everything I've sent are sitting in my 'sent' folder, and I have had no notification that any mail has been undeliverable.
I'm flumoxed - particularly since I'm still getting my quota of spam. I'll contact you again as soon as its possible to do so via normal email
