What if one of your more important Dutch clients is traveling abroad and needs
to e-mail you from some other country? Or even worse, your C.E.O. is in France
for a vacation, but wants to e-mail back an important document. Will he be happy?

There are other ways to increase your spam to ham ratios. I live in the United
States, where much spam originates, but I manage to kill the majority of it,
and usually have very few false negatives. Those are in the low scoring spam
range, and get their subjects adjusted to show that fact. I get very few
complaints about spam.
