FW: IP country block possible?

[Jeff A. Earickson]

Look at the IPBlock feature of MailScanner; see the list archives.
I use it to control (but not block) the amount of email per IP
number per region of the world.

If you simply want to block all non-Dutch IP numbers, why not do
it at the MTA level instead?  Or better yet, just unplug your
mail server -- blocking all non-Dutch numbers sounds a bit harsh.
