What is an E-mail Blacklist?
Generally, the term “blacklist” means to exclude. Within the context of e-mail, “blacklisting” is a way to prevent e-mail from reaching its intended recipient(s). On a mass scale, this is sometimes achieved when an Internet Service Provider (ISP) “blacklists” all e-mail sent by a specific originator. Originators of mass e-mails are often blacklisted by ISPs due to spam concerns. Many ISPs and independent organizations will often use databases of blacklisted e-mail originators to filter inbound e-mail on their servers to aid in preventing spam and to encourage Internet security.
