[Bob, you have the same problem but the fix is different; it looks as
 though you're sending messages with an invalid address and need a
 little rewriting to match what the list thinks you should be using.

 In the meantime, fixing your quoting styles and habits to match
 something like what is below would be *much* better.

What you are up against with lightning is that the current flowing
in a strike is in the order of 1 million amperes. Consequently if
the path to earth has just 0.10 ohm resistance there is still a
potential of 100,000 volts generated at the earthing point.
Such a large cuurent flowing will also generate quite large voltages
in even short lengths of wire in the near vicinty.
So the short answer is that nothing will protect your equipment
from direct hits or very near strikes. The only real protection
is to disconnect all equipment from the mains as soon as a thunder
storm nears.
