Hi,
my provider told me, that there are actually more than 200 spam emails per hour, they we're sent using our contact form. I'm using web-form-builder-full-osx-en-2.9-5557. The spam attack comes from russia, but there is no foreign php-script on my server. Will I have same problems with web form builder 2.10? Do you have any advices how to stop this thing?
This is the error message we got:

Thanx a lot, Rainer (from Germany)

Hi Rainer,
Do you want users from other countries to be able to use your form? If not block them with settings on your host.

Not at my computer right now to look but how do you do that Eric?

Hi Byron
Different hosting providers may have different ways you would be best asking your hosting providers technical services team, or have your client ask them if you don't have access to their hosting service
