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.
Imagine Carlos, um encanador que trabalha em Ackley, no estado do Iowa - com uma população de apenas 1.589 pessoas! Ele recebe seus fornecimentos de material de canalização ali de perto, sua família vive no mesmo estado e seu banco também é na mesma cidade. Essencialmente ele vive sua vida a nível local sem exposição internacional. Uma vez que todos o seu correio é originado nos Estados Unidos ele pode facilmente bloquear e-mail proveniente da China, da Índia ou do Zimbabue. Se algum e-mail vier desses locais ele vai ser considerado spam. De fato, Carlos pode bloquear todos os países exceto os Estados Unidos para reduzir o risco de algum spam passar pelo MX Guarddog e chegar em sua caixa de correio.
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.
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.
