I've just caught up on this:
> Yesterday, Thurs 25th March 1999, we had problems with our mailing
> software between the hours of 5.55pm and 8.50pm GMT
> Our systems administrator, Gavin Younger, fixed this problem as soon

So for anyone who had a post rejected as "user unknown" on
Thursday, try again!

We've also all had this:

That happens when someone sends a message to the list with
"confirm reading" switched on on their Emailer (here that was David
Douglas I think) and then someone else has their Emailer set so it
confirms they've read the message (here it was John Simons) but
that Emailer misbehaves and instead of confirming to the sender, it
confirms to the "reply-to" field: i.e. to all of us on the list.

This doesn't happen very often but it's a reason not to use read
confirmation or to allow your own software to confirm you've read
