I have been mailing a newsletter, usually a single side of A4 in Word attached, to club members for a number of years with no problem, but suddenly, with no changes to my PC etc, it refuses to send them. I use Windows Live Mail. It just comes up with 'Error'.
I tried to send the same thing on my friends PC too, (I am with Plusnet, he is with Sky) and the same thing happened. Also tried to send without any attachment but still no go.
