Hi all,
This isn't about spam, this is about blocking obvious attempts to
hack/connect to my submission port.
I know and understand the argument against just blanket blocking hosts
based on the country of origin, but I've recently been seeing random
connections on my submission port from hosts @ .ru and .cn domains.
The simple fact is, we do not have any users based *anywhere* but the
US, so, is what is the simplest way to block any/all non-US based client
connections on my submission port?
I'd also like to be able to whitelist certain domains, in the rare case
where someone might be on vacation abroad, and when they call me
complaining that they cannot send email, I can see the country they are
in my reject logs and whitelist that country temporarily.
Thanks,
