Care to finish that sentence off?  I can only guess at what you might
have said.

Though, I would have thought that on a server you really wouldn't want a
default input accept policy.  You'd have to be *very* *sure* that
everything on that server was internally ignoring connections that
shouldn't be allowed to the outside world.  At least a default deny/drop
incoming policy gives you some measure of protection against surprises.

I read messages from the public lists.
