Only noticed thi= s thanks to the threading in this list. My every day stuff doesn't get threaded (or pos= ted back to me) so I hadn't seen it before. I've corrected the time and sent a couple of tests to previously not workin= g addresses and I'll see what happens. Just a thought though, if for example, BT Internet was reject mail based on= my clock being so wrong, they'd do it for every customer...and they haven't. I don't= know, I'm out of ideas and pretty desperate now.
