Thanks Jon, was beginning to think that this forum was a Ghost Town.

I finally found a solution (?) which I posted over in SBS2K forum -
essentially I stopped ETRN'ing and went over to TURNing.  This had the
effect of sending (and receiving) the mail ok, with no accompanying Mystery
Data so the line closed fine after a few mins.  Gawd knows why, but it
brought my blood pressure back to normal again.

I picked up the 'Admin Exchange 2000 Server' book by Tulloch, which I'll
have to find time to pad through - guess I got a bit complacent with 4.5
being more intuitive.

I have to confess to whizzing over to your site initially, in the hope that
you'd already implemented Demon and SBS/ES2K!!!  Have you got a site counter
on that page??  I bet that it's had a fair view visitors, I know that I've
quoted the link extensively.
