Based in Germany, GMX is a widely-used e-mail service provider offering free accounts to consumers. It provides generous amounts of storage space, spam filtering, and supports access to multiple accounts through a single interface. Though many people access the service using a Web browser, GMX also supports the POP3 protocol. This allows you to configure your account to send and receive messages using third-party applications such as Microsoft Outlook Express. The account set-up process takes just minutes once you understand the proper steps.
