Draconian? Yeah probably... I agree there's a lot of spam generated within the US, but I can filter out Canada! ;) In my instance, I get a ton of foreign (outside the US) mail and 99% of it is spam. This methodology ultimately helps me cut down the "noise." Besides, if I do need to allow foreign mail inside, I can either whitelist the address/domain or allow the entire country in.
I guess the moral here is: your mileage may vary. -- Dave -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of David F.

After all, most spam originates in the US and Canada. (And we couldn't possibly implement such a policy; about 90% of our customers and 95% of our revenue are from a "foreign country." :-)) You can also get a free (but probably less accurate) database mapping IP address to country from http://ip-to-country.webhosting.info/ We use it on our Web site; if someone fills in a form claiming to be from Canada, but their IP address says Moldova, we treat the request with a little extra skepticism.
