Country Blocking

The country block is one of our most powerful, yet most underutilized blocklisting feature we offer. MX Guarddog makes it easy to block email originating from any country. Lets take a look at a couple of situations where this powerful blocklisting feature can be used.

Charles The Plummer

country block Imagine Charles, he is a plumber working in Ackley, Iowa - a population of only 1,589 people! He gets his plumbing supplies from the next town over, his family lives within the state and he banks with a local bank in his town. Essentially he is a local guy with no international exposure. Since all his email originates within the USA he can easily block email from China, India and Zimbabwe. If an email comes from these places it is going to be spam. In fact, Charles can essentially block all countries except the USA and greatly reduce the risk of any spam slipping past MX Guarddog into his mailbox.

Lars The Programmer

Lars is a computer programmer living and working in Berlin Germany, his sister lives in Brazil. His company is very tech savy, serving customers all over Europe. His company often gets emails from major IT companies in the USA and Canada.

Lars is having a major problem with spam originating from African countries, especially spam from Nigeria. Lars can safely block mail from Nigeria and other countries he does not expect any mail from - including Brazil.

But wait, if he blocks mail from Brazil how will his sister be able to reach him via email? Once blocked MX Guarddog will quarantine all mail coming from Brazil. Since Lars communicates regularly with his sister he has added his sister to his personal whitelist. The whitelist always takes priority over any blocklist, including the country blocklist. Lars will safely get email from his sister in Brazil but continue to block any other email originating from Brazil.

How About You?

If your organization has exposure to a limited number of countries you can safely use the country blocklist to place incoming mail from blocklisted countries into quarantine.

All email we stop will be placed into quarantine where you can review, release and whitelist any messages you require.

Accessing Country Blocklisting

All postmasters can access the country blocklist from the blocklisting filters page. You can also jump directly to the country blocklist tab and start selecting any country you don't want to receive mail from.
