Spamblocker block by country code domain

Might be handy to have an additional option similar to Geolocation but with the ability to block/allow certain country code top level domains. Or just check boxes of the top level domains you want to allow. There is no reason for us to get emails from a .br domain for example. I can go in and manually add I suppose, but there are 316 country code domains one or two of which I would only want to allow.

    Hi Chad,

    You're correct that you can add these already.
    We don't pre-populate a list like this because there aren't really any restrictions for where most domains are registered. (For example, lots of media sites use .tv despite that being a TLD for a country.) uses .ly, which is Lybia, etc.

    You can use geolocation, which is much more reliable a source about what server a piece of mail originated from (so long as it's not using a relay) and if you'd prefer to still block TLDs in the SMTP proxy, you can import/export your list as needed via proxy action.
