I think so; I'm basing this on experience with Derby and another application
(ie James not involved). But I believe my experience is backed up by the Derby
mission statement, claiming that the database directory can be simply
coy/pasted as required. That is my
mmers who know
very well there's hardly such thing as an open relay these days and that all
the ip addresses they've hacked are on blocklists very quickly.
