Hello, Ralf, & Mark,.

We running now, thanks for the help.

I will send out on my large list over the w/e (splitting the membership
just in case) and will report how the throttle patch performed. But on
a small list we are up, up, & away.

I'll look at verp next, don't want to have to tweak anything else so if
it's a standalone item to tick on/off as it were, then I'll do that.

Lots of nice questions on your list, with nicer answers. no rtfm all
the time.
